It would probably be those Illuminati, Bilderberg, Bohemian Grove and Mason thugs, and those big corporate banking thugs behind our economic collapse, the shooting in Norway, ETC...
Now who SHOULD it be? Absolutely nobody. We should disband the UN, EU, NATO, G7, G20, get rid of NAFTA, etc... If one country get's screwed with a bad government, at least there are others to go to, which is a great argument to make on a states' rights stance here in the US.
If I had no choice, though, I'd probably pick someone like Andrew Jackson, minus the bad treatment of minorities part, mainly because he didn't put up with banksters. Coolidge would be great, too, because he let people do what they want and just sat in office, doing almost nothing but lowering taxes and passing controversial immigration reform. That means he wasn't controlling people nor screwing people up, and the states managed just fine on their own.
