I have a lot of personal theories how my country can best cope with future geopolitical adjustments. If I were in charge, the first thing I would do would be to close most foreign military bases. We can have the strongest military in the world and have them largely based in the US. I think the US Navy continues to be a good investment, but I would cut back a small amount on intel and other military branches.

edit:
Since the U.S.'s war on terrorism, the U.S. has said that every trade done in dollars is de facto done on U.S. soil and thus subject to U.S. laws. I'm surprised that more countries have not tried to cut ties with the U.S. dollar.
