During the Korean War, General Douglas MacArthur pressured President Trumann to authorize the use of Nuclear Weapons against Chinese forces pushing into North Korea, and also to create a radioactive Buffer Zone between China and North Korea, and North and South Korea. Amongst other reasons, this led to MacArthur being relieved of his command of UN forces in Korea, only to have his successor make the same request.

Remember, China had no Nuclear Weapons at this time, and the USSR had few.
