You NEED the non-us poor guys to make all that dirt cheap stuff for your country j.
Like Nikes made for $1 in china that sell for $50-$100 retail. Computer bitz, cars, TV's, Fridges, clothes, furnishings etc etc.
If you dont want to deal with these places, we'll do it instead, and take the profits.
And if you dont want the foreigners oil, well the rest of us will have it, like the French and Russians carving up Iraq between them.
The bottom line is, you can't do without the non-US guys, especially their resources.
In return, you used to make the world a slightly safer place, and got respect for that.
9/11 was a pinprick for the US in the great scheme of things.
Hell, one US chemical company managed to wipe out 8000 people in an afternoon.

One of your biggest problems is this strange assertion that one American life is worth a hundred foreign johnnies.
Thats simply delusional, you seem to think like the aristocrats in France hundreds of years ago.
