A bit too much arrogance here, funboy51. America is the most indebted country in the world. Why would anybody, in the long run, want to trade for $$ any more? We all know the Dollar will collapse, the minute China says 'now'.
And if you don't need the mineral wealth, why don't you get out of Afghanistan?
And while you're at it, get out of the rest of the world as well, with your military bases and your invasion forces.
