Thailand (Siam)
After Japan's defeat in 1945, with the help of Seri Thai, Thailand was treated as a defeated country by the British and French, although American support mitigated the Allied terms. Thailand was not occupied by the Allies, but it was forced to return the territory it had regained to the British and the French. In the postwar period Thailand had relations with the United States, which it saw as a protector from the communist revolutions in neighbouring countries.
At the end of World War II, Japan was occupied by the Allied Powers, led by the United States with contributions also from Australia, India, New Zealand and the United Kingdom. This foreign presence marked the first time in its history that the island nation had been occupied by a foreign power. The San Francisco Peace Treaty, signed on September 8, 1951, marked the end of the Allied occupation, and after it came into force on April 28, 1952, Japan was once again an independent country.
During the occupation leading Japanese war crime charges were reserved for those who participated in a joint conspiracy to start and wage war, and were brought against those in the highest decision-making bodies; "Class B" crimes were reserved for those who committed "conventional" atrocities or crimes against humanity; "Class C" crimes were reserved for those in "the planning, ordering, authorization, or failure to prevent such transgressions at higher levels in the command structure."
Twenty-eight Japanese military and political leaders were charged with Class A crimes, and more than 5,700 Japanese nationals were charged with Class B and C crimes, mostly entailing prisoner abuse. China held 13 tribunals of its own, resulting in 504 convictions and 149 executions.
The Japanese Emperor Hirohito and all members of the imperial family such as Prince Asaka, were not prosecuted for involvement in any the three categories of crimes. Herbert Bix explains that "the Truman administration and General MacArthur both believed the occupation reforms would be implemented smoothly if they used Hirohito to legitimise their changes." As many as 50 suspects, such as Nobusuke Kishi, who later became Prime Minister, and Yoshisuke Aikawa, head of the zaibatsu Nissan, and future leader of the Chuseiren, were charged but released without ever being brought to trial in 1947 and 1948. Shiro Ishii received immunity in exchange for data gathered from his experiments on live prisoners. The lone dissenting judge to exonerate all indictees was Indian jurist Radhabinod Pal.
The tribunal was adjourned on 12 November 1948.
