Truman defined in one word.
Yalta.
And btw, Eisenhower who did a magnificent job in the European theatre considering who he was taking orders from,
argued against Hiroshima and Nagasaki.
Truman, the Senator from Organized Crime.
Truman didn’t attend Yalta. That was FDR. If Ike and others opposed use of the bomb, they were wrong. If you have a weapon that can end the war, you use it... period. You don’t sacrifice hundreds of thousands of American lives on an invasion of the Japanese mainland.
