American how do you feel about you world police status being tested?

Due to the collapse of the world economy countries will become more isolated and less likely to intervene in world situation. Countries will have to fend for themselves and will elect Nationalistic governments that sort out problems within as opposed to thousands of miles away. Obama's all talk about sorting out the worlds problems, you'll see with in the next few years. South Korea could defend against the North, and Israel could easily destroy Iran with the flick of a switch so I wouldn't worry. You'll see the collapse of all sort of organisations, from the EU to Nato and the UN all diminshed in power. People are fed up to the back teeth with being part of a world community.
