D-Day

"D-Day", "D Day" and "Operation Neptune" redirect here. For the use of D-Day as a general military term, see D-Day (military term). For other uses, see D-Day (disambiguation) and Operation Neptune (disambiguation). This article is about the first day of the Invasion of Normandy (D-Day). The subsequent operations are covered in Invasion of Normandy.The Normandy landings were the landing operations of the Allied invasion of Normandy, also known as Operation Neptune and Operation Overlord, during World War II. The landings commenced on Tuesday, 6 June 1944 (D-Day), beginning at 6:30 AM British Double Summer Time (UTC+2). In planning, D-Day was the term used for the day of actual landing, which was dependent on final approval. The assault was conducted in two phases: an air assault landing of 24,000 American, British, Canadian and Free French airborne troops shortly after midnight, and an amphibious landing of Allied infantry and armoured divisions on the coast of France commencing at 6:30 AM. There were also subsidiary 'attacks' mounted under the codenames Operation Glimmer and Operation Taxable to distract the German forces from the real landing areas.[4] The operation was the largest amphibious invasion of all time, with over 175,000[5] troops landing on 6 June 1944. 195,700[6] Allied naval and merchant navy personnel in over 5,000[5] ships were involved. The invasion required the transport of soldiers and materiel from the United Kingdom by troop-laden aircraft and ships, the assault landings, air support, naval interdiction of the English Channel and naval fire-support. The landings took place along a 50-mile (80 km) stretch of the Normandy coast divided into five sectors: Utah, Omaha, Gold, Juno and Sword.

Berlin Blockade + airlift

24 June 1948 - 12 May 1949) was one of the first major international crises of the Cold War and the first such crisis that resulted in casualties. During the multinational occupation of post-World War II Germany, the Soviet Union blocked the Western Allies' railway and road access to the sectors of Berlin under their control. Their aim was to force the western powers to allow the Soviet zone to start supplying Berlin with food and fuel, thereby giving the Soviets practical control over the entire city. In response, the Western Allies organized the Berlin Airlift to carry supplies to the people in West Berlin. Great Britain's Royal Air Force and the recently formed United States Air Force, flew over 200,000 flights over the time span of one year that provided 13,000 tons of daily necessities such as fuel and food to the people of Berlin [1]. By the spring of 1949, the effort was clearly succeeding, and by April the airlift was delivering more cargo than had previously flowed into the city by rail.

Truman

33rd prez.During World War I, Truman served as an artillery officer, making him the only president to have seen combat in World War I (his successor Eisenhower spent the war training tank crews in Pennsylvania). After the war he became part of the political machine of Tom Pendergast and was elected a county commissioner in Missouri and eventually a Democratic United States senator. After he gained national prominence as head of the wartime Truman Committee, Truman replaced vice president Henry A. Wallace as Roosevelt's running mate in 1944. Truman faced challenge after challenge in domestic affairs. The disorderly postwar reconversion of the economy of the United States was marked by severe shortages, numerous strikes, and the passage of the Taft-Hartley Act over his veto. He confounded all predictions to win re-election in 1948, helped by his famous Whistle Stop Tour of rural America. After his re-election he was able to pass only one of the proposals in his Fair Deal program. He used executive orders to begin desegregation of the military and to create loyalty checks which dismissed thousands of communist supporters from office, even though he strongly opposed mandatory loyalty oaths for governmental employees, a stance that led to charges that his administration was soft on communism. Truman's presidency was also eventful in foreign affairs, with the end of World War II and his decision to use nuclear weapons against Japan, the founding of the United Nations, the Marshall Plan to rebuild Europe, the Truman Doctrine to contain communism, the beginning of the Cold War, the Berlin Airlift, the creation of the North Atlantic Treaty Organization (NATO), Chinese Civil War, and the Korean War. Corruption in Truman's administration, which was linked to certain members in the cabinet and senior White House staff, was a central issue in the 1952 presidential campaign and helped cause Adlai Stevenson, Truman's successor for the Democratic nomination for president, to lose to Republican Dwight D. Eisenhower in the 1952 presidential election. "the buck ends here"

George Marshall

American military leader, Chief of Staff of the Army, Secretary of State, and the third Secretary of Defense. Once noted as the "organizer of victory" by Winston Churchill for his leadership of the Allied victory in World War II,[2] Marshall served as the U.S. Army Chief of Staff during the war and as the chief military adviser to President Franklin D. Roosevelt. As Secretary of State his name was given to the Marshall Plan, for which he was awarded the Nobel Peace Prize in 1953.[3]

Churchill

British politician known chiefly for his leadership of the United Kingdom during World War II. He is widely regarded as one of the great wartime leaders. He served as Prime Minister from 1940 to 1945 and again from 1951 to 1955. A noted statesman and orator, Churchill was also an officer in the British Army, a historian, writer and artist. To date, he is the only British Prime Minister to have received the Nobel Prize in Literature, and the first person to be recognised as an honorary citizen of the United States.After the outbreak of the Second World War, Churchill was again appointed First Lord of the Admiralty. Following the resignation of Neville Chamberlain on 10 May 1940, he became Prime Minister of the United Kingdom and led Britain to victory against the Axis powers. Churchill was always noted for his speeches, which became a great inspiration to the British people and to the embattled Allied forces. After losing the 1945 election, he became Leader of the Opposition. In 1951 he again became Prime Minister, before finally retiring in 1955. Upon his death, the Queen granted him the honour of a state funeral, which saw one of the largest assemblies of statesmen in the world.

fire bomb in japan

Damage to Tokyo's heavy industry was slight until firebombing destroyed much of the light industry that was used as an integral source for small machine parts and time-intensive processes. Firebombing also killed or made homeless many workers who had been taking part in war industry. Over 50% of Tokyo's industry was spread out among residential and commercial neighborhoods; firebombing cut their output in half.[7] The Imperial Palace was surrounded by areas destroyed by firebombing. The main Palace itself (Kyūden), home of the Imperial General Headquarters, took heavy damage by fire, even though bombing it was specifically prohibited by USAAF order.

hiroshima August 6, 1945

Hiroshima was the primary target of the first nuclear bombing mission on August 6, with Kokura and Nagasaki being alternative targets. August 6 was chosen because clouds had previously obscured the target. The 393d Bombardment Squadron B-29 Enola Gay, piloted and commanded by 509th Composite Group commander Colonel Paul Tibbets, was launched from North Field airbase on Tinian in the West Pacific, about six hours flight time from Japan. The Enola Gay (named after Colonel Tibbets' mother) was accompanied by two other B29s. The Great Artiste, commanded by Major Charles W. Sweeney, carried instrumentation; and a then-nameless aircraft later called Necessary Evil (the photography aircraft) was commanded by Captain George Marquardt.

V. E. Day

May 8, 1945, the date when the World War II Allies formally accepted the unconditional surrender of the armed forces of Nazi Germany and the end of Adolf Hitler's Third Reich The formal surrender of the occupying German forces in the Channel Islands was not until May 9, 1945. On 30 April Hitler committed suicide during the Battle of Berlin, and so the surrender of Germany was authorized by his replacement, President of Germany Karl Dönitz. The administration headed up by Dönitz was known as the Flensburg government. The act of military surrender was signed on 7 May in Reims, France, and ratified on 8 May in Berlin, Germany.

G. I. Bill

The G.I. Bill (officially titled Servicemen's Readjustment Act of 1944, P.L. 78-346, 58 Stat. 284m) was an omnibus bill that provided college or vocational education for returning World War II veterans (commonly referred to as G.I.s) as well as one year of unemployment compensation. It also provided many different types of loans for returning veterans to buy homes and start businesses. Since the original act, the term has come to include other veteran benefit programs created to assist veterans of subsequent wars as well as peacetime service.

Yalta Conference

The Yalta Conference, sometimes called the Crimea Conference and codenamed the Argonaut Conference, was the February 4-11, 1945 wartime meeting of the heads of government of the United States, the United Kingdom, and the Soviet Union—President Franklin D. Roosevelt, Prime Minister Winston Churchill, and General Secretary Joseph Stalin, respectively—for the purpose of discussing Europe's postwar reorganization. Mainly, it was intended to discuss the re-establishment of the nations of war-torn Europe. The conference convened in the Livadia Palace near Yalta, the Crimea. It was the second of three wartime conferences among the Big Three (Churchill, Roosevelt and Stalin). It had been preceded by the Tehran Conference in 1943, and it was followed by the Potsdam Conference which was attended by Harry S. Truman in place of the late Roosevelt; and Clement Attlee who attended in place of Churchill.

reasons of bombing

The goal of the weapon was to convince Japan to surrender unconditionally in accordance with the terms of the Potsdam Declaration. The Target Committee stated that "It was agreed that psychological factors in the target selection were of great importance. Two aspects of this are (1) obtaining the greatest psychological effect against Japan and (2) making the initial use sufficiently spectacular for the importance of the weapon to be internationally recognized when publicity on it is released.

baruch plan

a proposal by the United States government, written largely by Bernard Baruch but based on the Acheson-Lilienthal Report, to the United Nations Atomic Energy Commission (UNAEC) in its first meeting in June 1946. The United States, Great Britain and Canada called for an international organization to regulate atomic energy and President Truman responded by asking Undersecretary of State Dean Acheson and David Lilienthal to draw up a plan. The plan proposed to:[1] extend between all nations the exchange of basic scientific information for peaceful ends; implement control of nuclear power to the extent necessary to ensure its use only for peaceful purposes; eliminate from national armaments atomic weapons and all other major weapons adaptable to mass destruction; and establish effective safeguards by way of inspection and other means to protect complying States against the hazards of violations and evasions

George Kennan

was an American advisor, diplomat, political scientist, and historian, best known as "the father of containment" and as a key figure in the emergence of the Cold War. He later wrote standard histories of the relations between Russia and the Western powers.

V. J. Day

is a name chosen for the day on which the Surrender of Japan occurred, effectively ending World War II, and subsequent anniversaries of that event. The term has been applied to both the day on which the initial announcement of Japan's surrender was made in the afternoon of August 15, 1945 in Japan and to August 14, 1945 where it is observed as V-J Day in the United States when it was announced because of time zone differences in the Western Europe, the Americas, the Pacific Islands, and Australia and to September 2, 1945 when the formal signing of the surrender was made. The name V-J Day had been selected by the Allies after they named V-E Day for the victory in Europe.

United Nations

is an international organization whose stated aims are facilitating cooperation in international law, international security, economic development, social progress, human rights, and the achieving of world peace. The UN was founded in 1945 after World War II to replace the League of Nations, to stop wars between countries, and to provide a platform for dialogue. It contains multiple subsidiary organizations to carry out its missions.Following in the wake of the failed League of Nations (1919-1946) (which the United States never joined) the United Nations was established in 1945 to maintain international peace and promote cooperation in solving international economic, social and humanitarian problems. The earliest concrete plan for a new world organization was begun under the aegis of the U.S. State Department in 1939. Franklin D. Roosevelt first coined the term 'United Nations' as a term to describe the Allied countries. The term was first officially used on 1 January 1942 when 26 governments signed the Atlantic Charter, pledging to continue the war effort.[3] On 25 April 1945, the UN Conference on International Organization began in San Francisco, attended by 50 governments and a number of non-governmental organizations involved in drafting the Charter of the United Nations. The UN officially came into existence on 24 October 1945 upon ratification of the Charter by the five permanent members of the Security Council—France, the Republic of China, the Soviet Union, the United Kingdom and the United States—and by a majority of the other 46 signatories. The first meetings of the General Assembly, with 51 nations represented, and the Security Council, took place in Westminster Central Hall in London in January 1946.[4] Since its creation, there has been controversy and criticism of the UN organization. In the United States, an early opponent of the UN was the John Birch Society, which began a "get US out of the UN" campaign in 1959, charging that the UN's aim was to establish a "One World Government." After the Second World War, the French Committee of National Liberation was late to be recognized by the US as the government of France, and so the country was initially excluded from the conferences that aimed at creating the new organization. Charles de Gaulle criticized the UN, famously calling it le machin ("the thingie"), and was not convinced that a global security alliance would help maintaining world peace, preferring direct defence treaties between countries.[5]

nuclear arms

nuclear arms race was a competition for supremacy in nuclear warfare between the United States, the Soviet Union, and their respective allies during the Cold War. During the Cold War, in addition to the American and Soviet nuclear stockpiles, other countries also developed nuclear weapons, though none engaged in warhead production on nearly the same scale as the two superpowers.

McCarthy

oseph Raymond McCarthy (November 14, 1908 - May 2, 1957) was an American politician who served as a Republican U.S. Senator from the state of Wisconsin from 1947 until his death in 1957. Beginning in 1950, McCarthy became the most visible public face of a period in which Cold War tensions fueled fears of widespread Communist subversion.[1] He was noted for making claims that there were large numbers of Communists and Soviet spies and sympathizers inside the United States federal government and elsewhere. Ultimately, McCarthy's tactics and his inability to substantiate his claims led him to be censured by the United States Senate. The term McCarthyism, coined in 1950 in reference to McCarthy's practices, was soon applied to similar anti-communist activities. Today the term is used more generally to describe demagogic, reckless, and unsubstantiated accusations, as well as public attacks on the character or patriotism of political opponents.[2] Born and raised on a Wisconsin farm, McCarthy earned a law degree at Marquette University in 1935 and was elected as a circuit judge in 1939, the youngest in state history.[3] At age 33, McCarthy volunteered for the United States Marine Corps and served during World War II. He successfully ran for the United States Senate in 1946, defeating Robert M. La Follette, Jr. After several largely undistinguished years in the Senate, McCarthy rose suddenly to national fame in February 1950 when he asserted in a speech that he had a list of "members of the Communist Party and members of a spy ring" who were employed in the State Department.[4] McCarthy was never able to prove his sensational charge. In succeeding years, McCarthy made additional accusations of Communist infiltration into the State Department, the administration of President Truman, Voice of America, and the United States Army. He also used charges of communism, communist sympathies, or disloyalty to attack a number of politicians and other individuals inside and outside of government. With the highly publicized Army-McCarthy hearings of 1954, McCarthy's support and popularity began to fade. On December 2, 1954, the Senate voted to censure Senator McCarthy by a vote of 67 to 22, making him one of the few senators ever to be disciplined in this fashion. McCarthy died in Bethesda Naval Hospital on May 2, 1957, at the age of 48. The official cause of death was acute hepatitis; it is widely accepted that this was exacerbated by alcoholism.[5]

lend + lease

program under which the United States of America supplied the United Kingdom, the Soviet Union, China, France and other Allied nations with vast amounts of war material between 1941 and 1945 in return for, in the case of Britain, military bases in Newfoundland, Bermuda, and the British West Indies. It began in March 1941, over 18 months after the outbreak of the European war in September 1939, but before the U.S. entrance into the war in December 1941. It was called An Act Further to Promote the Defense of the United States. This act also ended the pretense of the neutrality of the United States. Hitler recognized this and consequently had submarines attack US ships such as the SS Robin Moor, an unarmed merchant steamship destroyed by a German U-boat on 21 May, 1941 outside of the war zone.

cash + carry

t a special session of the United States Congress on 21 September 1939, as World War II was spreading throughout Europe, US President Franklin D. Roosevelt requested the policy of cash and carry replace the Neutrality Acts of 1936. The revision allowed the sale of material to belligerents, as long as the recipients arranged for the transport using their own ships and paid immediately in cash. The purpose was to hold neutrality between the United States and European countries, while still giving material aid to Britain (without the need to extend the same such aid to Germany on account of the fact that the Germans had no funds and that British control of the Atlantic sea lanes also prevented them collecting any material). Various policies forbade selling implements of war or lending money to belligerent countries under any terms.[clarification needed] The economic situation in the US was rebounding at this time (after the Great Depression) but there was still a need for industrial manufacturing jobs. The Cash and Carry program helped to solve this issue and in turn Great Britain benefited from the purchase of arms and other goods. This act also made sure that the US did not give away all its supplies and rations. The program was also aimed at preventing American intervention in the war, and required the buyers to send their own ships to American ports and assume all risk in transportation. US shipping interests were forbidden from entering into conflict zones. This program also required all payments in cash currency, rather than on credit, preventing US businesses interests backing the success or failure of any warring nation. Because of the conclusion of the Nye Committee, which asserted that United States involvement in World War I was driven by private interests from arms manufacturers, many Americans believed that investment in a belligerent would eventually lead to American participation in war.

MacArthur

was an American general and field marshal of the Philippine Army. He was a Chief of Staff of the United States Army during the 1930s and played a prominent role in the Pacific theater during World War II. He received the Medal of Honor for his service in the Philippines Campaign. Arthur MacArthur, Jr., and Douglas MacArthur were the first father and son to each be awarded the medal. He was one of only five men ever to rise to the rank of general of the army in the U.S. Army, and the only man to become a field marshal in the Philippine Army. Douglas MacArthur was raised as a military brat in the American Old West. He attended the West Texas Military Ac

truman doctrine

the common name for the Cold War strategy of containment versus the Soviet Union and the expansion of communism. This doctrine was first promulgated by President Harry Truman in an address to the U.S. Congress on March 12, 1947.[1]President Truman, who was supported by Senator Arthur H. Vandenberg and the Republican-controlled Congress, promulgated this doctrine after Prime Minister Tsaldaris of Greece visited Washington in December 1946 to ask for additional American assistance.[7] Aid was agreed by the United States government to be given to both Greece and Turkey. It was an early response to a perceived political involvement by the Soviet Union in Europe and Asia, as suggested by the Communist movements in Turkey and Greece. The situation was perceived as very important for American balance of power politics in the context of the cold war: "If Greece was lost, Turkey would become an untenable outpost in a sea of communism. Similarly, if Turkey yielded to Soviet demands, the position of Greece would be extremely endangered."[8] It was a regional domino effect threat that guided the United States' decision. The United States was cautious of a third World War at this time, and needed military advantages over the Soviet Union if they were to win. Greece and Turkey turned out to be very important: "the failure of the West to prevent a communist takeover in Greece would not only put the Russians on a particularly dangerous flank for the Turks, but strengthen the Soviet Union's ability to cut off allied supplies and assistance in the event of war."[9] The Truman Doctrine was the first in a series of containment moves by the United States, followed by economic restoration of Western Europe through the Marshall Plan and military containment by the creation of NATO in 1949. In Truman's words, it became "the policy of the United States to support free peoples who are resisting attempted subjugation by armed minorities or by outside pressures." Using a framing rhetoric that continues to have resonance today, Truman reasoned that because these "totalitarian regimes" coerced "free peoples," they represented a threat to international peace and the national security of the United States. Countries in opposition of the Truman Doctrine feared that the United States alone could not contain communism and protect free countries. Disregarding the disapproval of some countries, Truman went forth and passed the bill.[10] President Truman made the proclamation in an address to the U.S. Congress on March 12, 1947, amid the crisis of the Greek Civil War (1946-1949). Truman insisted that if Greece and Turkey did not receive the aid that they needed, they would inevitably fall to Communism with consequences throughout the region.

marshall plan

the primary program, 1947-51, of the United States for rebuilding and creating a stronger economic foundation for the countries of Western Europe. The initiative was named for Secretary of State George Marshall and was largely the creation of State Department officials, especially William L. Clayton and George F. Kennan. George Marshall spoke of the administration's desire to help the European recovery in his address at Harvard University in June 1947.[1] The reconstruction plan, developed at a meeting of the participating European states, was established on June 5, 1947. It offered the same aid to the USSR and its allies, but they did not accept it.[2][3] The plan was in operation for four years beginning in April 1948. During that period some US $13 billion in economic and technical assistance were given to help the recovery of the European countries that had joined in the Organization for European Economic Co-operation. This $13 billion was in the context of a U.S. GDP of $258 billion in 1948, and was on top of $12 billion in American aid to Europe between the end of the war and the start of the Plan.[4]

pearl harbor

unannounced military strike conducted by the Imperial Japanese Navy against the United States naval base at Pearl Harbor, Hawaii on the morning of December 7, 1941. It resulted in the United States' entry into World War II. The attack was intended as a preventive action in order to keep the U.S. Pacific Fleet from influencing the war that the Empire of Japan was planning in Southeast Asia, against Britain and the Netherlands, as well as the U.S. in the Philippines. The base was attacked by Japanese aircraft (a total of 353, in two waves) launched from six aircraft carriers.[7] Four U.S. Navy battleships were sunk (two of which were raised and returned to service later in the war) and all of the four other battleships present were damaged. The Japanese also sank or damaged three cruisers, three destroyers, an anti-aircraft training ship[8] and one minelayer. 188 U.S. aircraft were destroyed, 2,402 personnel were killed[9] and 1,282 were wounded. The power station, shipyard, maintenance, and fuel and torpedo storage facilities, as well as the submarine piers and headquarters building (also home of the intelligence section) were not attacked. Japanese losses were light, with 29 aircraft and five midget submarines lost, and 65 servicemen killed or wounded. One Japanese sailor was captured. The attack was a major engagement of World War II and came as a profound shock to the American people. Domestic support for isolationism, which had been strong, disappeared. Germany's ill-considered declaration of war on the U.S., which was not required by any treaty commitment, moved the U.S. from clandestine support of Britain (for example the Neutrality Patrol) into active alliance and full participation in the European Theater. Despite numerous historical precedents for unannounced military action, the lack of any formal warning by Japan, particularly while negotiations were still apparently ongoing, led to it being characterized as a "sneak attack", and to President Franklin D. Roosevelt proclaiming December 7 "a date which will live in infamy".

nagasaki August 9, 1945

was not the primary location to drop the bomb, it was the second choice and only option afterward. At 11:01, a last minute break in the clouds over Nagasaki allowed Bockscar's bombardier, Captain Kermit Beahan, to visually sight the target as ordered. The "Fat Man" weapon, containing a core of ~6.4 kg (14.1 lbs.) of plutonium-239, was dropped over the city's industrial valley. It exploded 43 seconds later at 469 meters (1,540 ft) above the ground exactly halfway between the Mitsubishi Steel and Arms Works in the south and the Mitsubishi-Urakami Ordnance Works (Torpedo Works) in the north. This was nearly 3 kilometers (2 mi) northwest of the planned hypocenter; the blast was confined to the Urakami Valley and a major portion of the city was protected by the intervening hills.[59] The resulting explosion had a blast yield equivalent to 21 kilotons of TNT (88 TJ).[60] The explosion generated heat estimated at 3,900 degrees Celsius (4,200 K, 7,000 °F) and winds that were estimated at 1005 km/h (624 mph).

Stalin

was the first General Secretary of the Communist Party of the Soviet Union's Central Committee from 1922 until his death in 1953. In the years following Lenin's death in 1924, he rose to become the leader of the Soviet Union. Stalin launched a command economy, replacing the New Economic Policy of the 1920s with Five-Year Plans and launching a period of rapid industrialization and economic collectivization. The upheaval in the agricultural sector disrupted food production, resulting in widespread famine, such as the catastrophic Soviet famine of 1932-1933, known in Ukraine as the Holodomor.[3] During the late 1930s, Stalin launched the Great Purge (also known as the "Great Terror"), a campaign to purge the Communist Party of people accused of sabotage, terrorism, or treachery; he extended it to the military and other sectors of Soviet society. Targets were often executed, imprisoned in Gulag labor camps or exiled. In the years which followed, millions of members of ethnic minorities were also deported.[4][5] In 1939, after failed attempts to establish a collective security system in Europe, Stalin decided to enter into a non-aggression pact with Nazi Germany, followed by a Soviet invasion of Poland, Finland, the Baltics, Bessarabia and northern Bukovina. After Germany violated the pact in 1941, the Soviet Union joined the Allies to play a primary role in the Axis defeat, at the cost of the largest death toll for any country in the war (mostly due to the mass deaths of civilians on the territories occupied by Nazis). After the war Stalin installed communist governments in most of Eastern Europe, forming the Eastern bloc, behind what was referred to as an "Iron Curtain" of Soviet rule during the long period of antagonism between the Western world and the USSR, known as the Cold War. Stalin fostered a cult of personality around him, but after his death, his successor, Nikita Khrushchev, denounced his legacy and drove the process of de-Stalinization of the Soviet Union.[6]

Maragret Chase Smith

was the first to stand up to McCarthy. always wore a rose. Republican Senator from Maine, and one of the most successful politicians in Maine history.[1] She was the first woman to be elected to both the U.S. House and the Senate, and the first woman from Maine to serve in either.[2] She was also the first woman to have her name placed in nomination for the U.S. Presidency at a major party's convention (1964 Republican Convention, won by Barry Goldwater).[3] She was a liberal Republican, included with those known as Rockefeller Republicans. When she left office, Smith had the record as the longest-serving female senator in United States history, ranking 11th in seniority among the members of the Senate, a distinction that has not been surpassed.

japanese interment

was the forced relocation and internment by the United States government in 1942 of approximately 110,000 Japanese Americans and Japanese residing along the Pacific coast of the United States to camps called "War Relocation Camps," in the wake of Imperial Japan's attack on Pearl Harbor.[1][2] The internment of Japanese Americans was applied unequally throughout the United States. Japanese Americans residing on the West Coast of the United States were all interned, whereas in Hawaii, where more than 150,000 Japanese Americans composed nearly a third of that territory's population, 1,200[3] to 1,800 Japanese Americans were interned.[4] Of those interned, 62% were American citizens.[5][6] President Franklin Delano Roosevelt authorized the internment with Executive Order 9066 on February 19, 1942, which allowed local military commanders to designate "military areas" as "exclusion zones," from which "any or all persons may be excluded." This power was used to declare that all people of Japanese ancestry were excluded from the entire Pacific coast, including all of California and most of Oregon and Washington, except for those in internment camps.[7] In 1944, the Supreme Court upheld the constitutionality of the exclusion orders,[8] while noting that the provisions that singled out people of Japanese ancestry were a separate issue outside the scope of the proceedings.[9] The United States Census Bureau assisted the internment efforts by providing confidential neighborhood information on Japanese Americans. The Bureau's role was denied for decades but was finally proven in 2007.[10][11] In 1988, Congress passed and President Ronald Reagan signed legislation which apologized for the internment on behalf of the U.S. government. The legislation stated that government actions were based on "race prejudice, war hysteria, and a failure of political leadership".[12] Over $1.6 billion in reparations were later disbursed by the U.S. government to Japanese Americans who had either suffered internment or were heirs of those who had suffered internment.[13]
