Truman:
1 Dropped the atomic bombs on Japan, The atomization of Hiroshima and Nagasaki was a war of more scope than any of the Japanese generals were executed for. If Harry Truman was not a war criminal, then no one ever was.
2 Championed the development of the hydrogen bomb, which makes Fat Man and Little Boy look like firecrackers.
3 The horrific Taft-Hartley Act passed on his watch, and he utterly failed in his attempts to repeal it, thus gutting the Wagner Act, and sowing the foundational seeds of union destruction for the next 60 years
4 Was the first Cold Warrior president, giving left cover to take-over of the US foreign policy by the military-industrial complex
4 Korean War, which he labeled a police action (continuing the War on Terror, anyone?)
5 Failed at true universal health care
6 Tried and failed to push through Universal Military Training (Obama with the mandatory universal service failed as well)
7 Supported enthusiastically the creation of the CIA (enough said there).
8 NATO created with his support, which performed (Opertion Gladio) terrible false-flag terror acts here in the EU for years, killing hundreds.
http://en.wikipedia.org/wiki/Operation_Gladio 9 Supported National Security Council Resolution NSC-68 in 1948 (it was classified till 1975), which declared, "a defeat of free institutions anywhere is a defeat everywhere." thus completing redefining American geo-political strategy into a global empire.NSC-48 called for an immediate 300 to 400% increase in military spending, thus military Keynesianism was permanently entrenched.
10 Decimated Article 1, section 8 of the U.S. Constitution (the power of waging war rests solely in Congress) by usurping that power when he stated formally - "The president, as Commander-in-Chief of the Armed Forces of the United States, has full control over the use thereof."
11 Tried to draft striking railroad workers in the US Army. Only the unlikely alliance of old-right Senator Robert Taft of Ohio and left liberal Claude Pepper of Florida stopped this.
12 Executive Order 10340, where Truman tried to have the US Army seize the steel mills of the USA to stop a national strike by the unions. Defeated by the US Supreme Court in Youngstown Sheet & Tube Co. v. Sawyer.
13 Supported the UN ramming through of the partition of Palestine, and the creation of Israel, despite privately writing to Eleanor Roosevelt "I fear very much that the Jews are like all underdogs. When they get on top, they are just as intolerant and as cruel as the people were to them when they were underneath. I regret this situation very much, because my sympathy has always been on their side."
14 Issued Executive Order 9835 which, in 1947, set up loyalty boards to investigate espionage among federal employees.
15 "THE BUCK STOPS HERE", still waiting on Obama for this one.
