Problem solved- isolate the US?

I think we should isolate ourselves militarily, because we do have this global-military presence, and we do act like the world's policeman, which is too expensive, and put's an American life at risk for those pesky politicians. I think we should cut off all aid, especially to Israel, and mind our own business. We cannot isolate ourselves from the world in a blink of an eye, but we can just trade and talk with every nation, and stop intervening in people's affairs. In my opinion, the word "non-interventionism" would be a more suitable policy. Take care.
