Tucker derangement syndrome is real.

“It always appeared to us that, atomic bomb or no atomic bomb, the Japanese were already on the verge of collapse.” -General Henry H. Arnold Commanding General of the U.S. Army Air Forces Under President Truman

“Japan was at the moment seeking some way to surrender with minimum loss of ‘face’. It wasn’t necessary to hit them with that awful thing.”
– General Dwight D. Eisenhower

Needless to say every American has a right to evaluate whether the drastic measure of dropping a nuke on a non-military target in a country that had been on the defense for two years (plus negotiating their surrender) was necessary.

You may ultimately conclude it was or wasn’t not— but your right to think critically and express your views is about as American as it gets.
