It's really doesn't logically follow to blame the United States' alleged impending doom on Obama. This current crisis is less the result of Obamanomics or whatever the idiots at Fox News are calling it and more the inevitable consequence of a government that for decades followed a policy of borrowing money to finance a massive, worldwide military presence. No matter what you think of him, I don't think he (nor anyone else) ever had much of a chance of fixing the mess.
I am not a supporter of Obama nor of democracy, though I think calling Hitler more "correct" (is there ever a "correct" way of doing things or looking at the world? Pointless question, I think I can anticipate your answer) is bit of stretch. Militant fascism is, at its core, as base and populist as American democracy, only less stable.
