Harry S. Truman (1945-1953)

Horrible. First of all, the decision to drop the bomb had already been made; but, if you want to give him credit for that, so be it. He decimated our military starting in 1945 then wanted to use it in 1950. Many of the first soldiers and Marines in Korea didn't even have ammo rounds for their clips. MIGs had a field day, blowing our antiquated B-29's out of the sky like shooting fish in a barrel. This guy was the godfather and originator of the "no-win policy". His bumbling also served to cause a recession by the time he was kicked out on his rump.
