Maybe my questions were not clear enough:

Obviously it the US would loose the ability to beat every other nation whenever they want. They would be forced to co-operate. And it would cost jobs at once. On the onther side they could save millions and decrease taxes. That should increase their economy and create new jobs.
The US would be forced to work together with their allies (NATO) and the UN. They would try to reform the UN. They would be leading again instead of walking alone.

The US is like a man who carries a big gun to be respected and complains that nobody loves him.
