When I speak of imposing sanctions and political/economical barriers between countries who tend to go in the wrong way, I don't mean a militaristic, arrogant one-sided intervention. I don't mean a coup. I mean a UN based movement, based on international laws. Does anyone here remember Slobodan Milosevic's case? Do you see how North Korea's case is being treated? Also, why hasn't the US or UK interfered on Idi Amin Dada back in the 70s? Think about it.
I wouldn't think China is a problem, as I feel they are slowly moving into a democracy, pressured by the chinese and international market. I would be sure they slowly move into a peaceful resolution for organizing free elections, even if indirect ones at first. I wouldn't worry about Hugo Chavez as well, he has little to no international influence and is only slowly moving his country back to the 1800s. I say let him rule his way down, should be fun to watch. Brazil's gonna help Venezuela when he is overthrown (which should happen in a few years).
