Asked in Nuclear Weapons
Who wanted to use nuclear weapons against the Chinese during the Korean war?
General Douglas MacArthur suggested this, resulting in President Harry Truman terminating MacArthur's military career on April 10, 1951 and replacing him with General Matthew Ridgway.
The Korean War began on June 25, 1950 and an armistice was signed on July 27, 1953. Note: Truman had already had 4 MK-4 fission bombs shipped to Korea but had not authorized their use (so when MacArthur threatened to use fission bombs he could have but it would have been unauthorized).
