Long term it is a very tough position for the US. They need to run a trade deficit to keep the power of the US dollar, if that goes so does a lot of their world power.

More broadly however, the question that I think everyone should ponder on is, "If the US falls as the world super power, do you think the alternative will be better?"

A huge part of the US's spending is on the military and that is used to stabilize global trade, that is so that the USD is still THE major currency. But recent moves looks like they are trying to keep that while also kicking out the struts that hold up the entire system. It is very illogical, maybe there is a bigger plan but somehow I don't think there is.
