Truman was “the buck stops here” President.
He was the one who dropped the bomb on Japan.
Right or wrong, he was not going to fight a war on both sides of the world... he was done losing lives.. and Japan had to surrender. they did...
for whatever history reports.. he ended the war with Japan. and Japan was headed to the west coast of America. The surrender was a nice piece of work.
In your dreams, and it wasn't Truman that defeated Japan it was President Roosevelt, Gen MacArthur and Adm Nimitz. Truman did not take over until the middle of April in 45, the war was all but over by then.
