One question; what does SCAP stand for please? Thank you.
Supreme Commander for the Allied Powers (SCAP) was the title held by General Douglas MacArthur
The Supreme Commander for the Allied Powers (SCAP) (originally briefly styled Supreme Commander of the Allied Powers[1]) was the title held by General Douglas MacArthur during the Allied occupation of Japan following World War II.
In Japan, the position was generally referred to as GHQ (General Headquarters), as SCAP also referred to the offices of the occupation, including a staff of several hundred U.S. civil servants as well as military personnel. Some of these personnel effectively wrote a first draft of the Japanese Constitution, which the National Diet then ratified after a few amendments. Australian, British, Indian, and New Zealand forces under SCAP were organized into a sub-command known as British Commonwealth Occupation Force.
