The Battle of Okinawa, codenamed Operation Iceberg, was a battle of the Pacific War fought on the island of Okinawa by United States Army and United States Marine Corps forces against the Imperial Japanese Army. The initial invasion of Okinawa on 1 April 1945 was the largest amphibious assault in the Pacific Theater of World War II. The Kerama Islands surrounding Okinawa were preemptively captured on 26 March by the 77th Infantry Division. The 82-day battle lasted from 1 April until 22 June 1945. After a long campaign of island hopping, the Allies were planning to use Kadena Air Base on the large island of Okinawa as a base for Operation Downfall, the planned invasion of the Japanese home islands, 340 mi (550 km) away.
The Korean War was fought between North Korea and South Korea from 1950 to 1953. The war began on 25 June 1950 when North Korea invaded South Korea following clashes along the border and rebellions in South Korea. North Korea was supported by China and the Soviet Union while South Korea was supported by the United States and allied countries. The fighting ended with an armistice on 27 July 1953.
The Potsdam Conference was held at Potsdam in the Soviet occupation zone from July 17 to August 2, 1945, to allow the three leading Allies to plan the postwar peace, while avoiding the mistakes of the Paris Peace Conference of 1919. The participants were the Soviet Union, the United Kingdom, and the United States. They were represented respectively by General Secretary Joseph Stalin, Prime Ministers Winston Churchill and Clement Attlee, and President Harry S. Truman. They gathered to decide how to administer Germany, which had agreed to an unconditional surrender nine weeks earlier. The goals of the conference also included establishing the postwar order, solving issues on the peace treaty, and countering the effects of the war.
George Catlett Marshall Jr. was an American army officer and statesman. He rose through the United States Army to become Chief of Staff of the U.S. Army under Presidents Franklin D. Roosevelt and Harry S. Truman, then served as Secretary of State and Secretary of Defense under Truman. Winston Churchill lauded Marshall as the "organizer of victory" for his leadership of the Allied victory in World War II. After the war, he spent a frustrating year trying and failing to avoid the impending Chinese Civil War. As Secretary of State, Marshall advocated for a U.S. economic and political commitment to post-war European recovery, including the Marshall Plan that bore his name. In recognition of this work, he was awarded the Nobel Peace Prize in 1953, the only Army general ever to be so honored.
Douglas MacArthur was an American military leader who served as General of the Army for the United States, as well as a field marshal to the Philippine Army. He served with distinction in World War I, was Chief of Staff of the United States Army during the 1930s, and played a prominent role in the Pacific theater during World War II. MacArthur was nominated for the Medal of Honor three times, and received it for his service in the Philippines campaign. This made him along with his father Arthur MacArthur Jr. the first father and son to be awarded the medal. He was one of only five men to rise to the rank of General of the Army in the U.S. Army, and the only one conferred the rank of field marshal in the Philippine Army.
Henry Lewis Stimson was an American statesman, lawyer, and Republican Party politician. Over his long career, he emerged as a leading figure in U.S. foreign policy by serving in both Republican and Democratic administrations. He served as Secretary of War (1911–1913) under President William Howard Taft, Secretary of State (1929–1933) under President Herbert Hoover, and again Secretary of War (1940–1945) under Presidents Franklin D. Roosevelt and Harry S. Truman, overseeing American military efforts during World War II.
Operation Downfall was the proposed Allied plan for the invasion of the Japanese home islands near the end of World War II. The planned operation was canceled when Japan surrendered following the atomic bombings of Hiroshima and Nagasaki, the Soviet declaration of war, and the invasion of Manchuria. The operation had two parts: Operation Olympic and Operation Coronet. Set to begin in November 1945, Operation Olympic was intended to capture the southern third of the southernmost main Japanese island, Kyūshū, with the recently captured island of Okinawa to be used as a staging area. In early 1946 would come Operation Coronet, the planned invasion of the Kantō Plain, near Tokyo, on the main Japanese island of Honshu. Airbases on Kyūshū captured in Operation Olympic would allow land-based air support for Operation Coronet. If Downfall had taken place, it would have been the largest amphibious operation in history, surpassing D-Day.
The Cold War was a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. Cold war is used because there was no large-scale fighting directly between the two superpowers, but they each supported opposing sides in major regional conflicts known as proxy wars. The conflict was based on the ideological and geopolitical struggle for global influence by these two superpowers, following their roles as the Allies of World War II that led to victory against Nazi Germany and Imperial Japan in 1945. Aside from the nuclear arms race and conventional military deployment, the struggle for dominance was expressed via indirect means, such as psychological warfare, propaganda campaigns, espionage, far-reaching embargoes, sports diplomacy, and technological competitions like the Space Race.
General Albert Coady Wedemeyer was a United States Army commander who served in Asia during World War II from October 1943 to the end of the war. Previously, he was an important member of the War Planning Board which formulated plans for the invasion of Normandy. He was General George C. Marshall's chief consultant when in the Spring of 1942 he traveled to London with General Marshall and a small group of American military men to consult with the British in an effort to convince the British to support the cross channel invasion. Wedemeyer was a staunch anti-communist. While in China during the years 1944 to 1945 he was Chiang Kai-shek's Chief of Staff and commanded all American forces in China. Wedemeyer supported Chiang's struggle against Mao Zedong and in 1947 President Truman sent him back to China to render a report on what actions the United States should take. During the Cold War, Wedemeyer was a chief supporter of the Berlin Airlift.
The surrender of the Empire of Japan in World War II was announced by Emperor Hirohito on 15 August and formally signed on 2 September 1945, bringing the war's hostilities to a close. By the end of July 1945, the Imperial Japanese Navy (IJN) had become incapable of conducting major operations and an Allied invasion of Japan was imminent. Together with the United Kingdom and China, the United States called for the unconditional surrender of the Japanese armed forces in the Potsdam Declaration on 26 July 1945—the alternative being "prompt and utter destruction". While publicly stating their intent to fight on to the bitter end, Japan's leaders were privately making entreaties to the publicly neutral Soviet Union to mediate peace on terms more favorable to the Japanese. While maintaining a sufficient level of diplomatic engagement with the Japanese to give them the impression they might be willing to mediate, the Soviets were covertly preparing to attack Japanese forces in Manchuria and Korea in fulfillment of promises they had secretly made to the United States and the United Kingdom at the Tehran and Yalta Conferences.
Harry S. Truman was the 33rd president of the United States, serving from 1945 to 1953. A member of the Democratic Party, he previously served as the 34th vice president from January to April 1945 under Franklin D. Roosevelt and as a United States senator from Missouri from 1935 to January 1945. Assuming the presidency after Roosevelt's death, Truman implemented the Marshall Plan to rebuild the economy of Western Europe and established both the Truman Doctrine and NATO to contain the expansion of Soviet communism. He proposed numerous liberal domestic reforms, but few were enacted by the conservative coalition that dominated the Congress.
On 6 and 9 August 1945, the United States detonated two atomic bombs over the Japanese cities of Hiroshima and Nagasaki. The bombings killed between 129,000 and 226,000 people, most of whom were civilians, and remain the only use of nuclear weapons in an armed conflict. Japan surrendered to the Allies on 15 August, six days after the bombing of Nagasaki and the Soviet Union's declaration of war against Japan and invasion of Japanese-occupied Manchuria. The Japanese government signed the instrument of surrender on 2 September, effectively ending the war.
Substantial debate exists over the ethical, legal, and military aspects of the atomic bombings of Hiroshima and Nagasaki on 6 August and 9 August 1945 at the close of World War II (1939–45).
This is a timeline of the events that stretched over the period of late World War II, its conclusion and legal aftermath, from January 1945 to 1991.
Charles Alan Pownall was a vice admiral in the United States Navy and Governor of Guam. He was the third military Governor and first naval Governor of Guam following the United States recapture of the island from the Japanese. After conflict with the Guam Congress in 1948, Pownall replaced many Congressmen with his own appointments, whom the Guamanians refused to recognize. The ensuing protest persuaded President Truman to transfer control of the island away from the Navy. As a consequence, Charles Pownall was the last military governor of Guam.
Asian Americans, who are Americans of Asian descent, have fought and served on behalf of the United States since the American Revolutionary War. During the American Civil War Asian Americans fought for both the Union and the Confederacy. Afterwards Asian Americans served primarily in the U.S. Navy until the Philippine–American War.
On 11 April 1951, U.S. president Harry S. Truman relieved General of the Army Douglas MacArthur of his commands after MacArthur made public statements that contradicted the administration's policies. MacArthur was a popular hero of World War II who was then commander of United Nations Command forces fighting in the Korean War, and his relief remains a controversial topic in the field of civil–military relations.
The military history of the United States during the Korean War began after the defeat of Japan by the Allied Powers in World War II. This brought an end to 35 years of Japanese occupation of the Korean Peninsula and led to the peninsula being divided into two zones; a northern zone occupied by the Soviet Union and a southern zone occupied by the United States. After negotiations on reunification failed, the latter became the Republic of Korea or South Korea in August 1948 while the former became the Democratic People's Republic of Korea or North Korea in September 1948.
The main issues of the United States foreign policy during the 1945–1953 presidency of Harry S. Truman include:
During the Soviet–Japanese War in August 1945, the Soviet Union made plans to invade Hokkaido, the northernmost of Japan's four main home islands. Opposition from the United States and doubts within the Soviet high command caused the plans to be cancelled before the invasion could begin.
