1. MacArthur took part in the massacre of the Bonus Army. Never forget that.
Hiroshima and Nagasaki saved MILLIONS by ending the war. That makes Truman OK in my book.
More members of the Bonus Army died at the hands of Roosevelt(258 veterans sent to the Florida Keys as part of the CCC that were killed by the Labor day Hurricane of 1935)then died at the Bonus Army Massacre(4 veterans, two killed by DC police two more killed when MacArther ordered the removal of the bonus Army from DC and one infant miscarried during the event).
It can be said that The whole Bonus army episode was orchestrated by the same people that wanted FDR to be President, you know the Democrats as well as those in Big Business that wanted General Smedley D. Butler to overthrow the government and use FDR as a puppet or a figurehead.
Faced with the very real possibility that Big Business was going to seize power through the Bonus Army Butler told them that he would raise a larger force and save the nation if they tried.
