Hmmm. Jerry Pournelle -- and others -- like to say that the US crushed the Soviet Union by making them spend till they died trying to keep up with us in space, in arms, and in Southeast Asia. The "Seventy Years War," I believe Pournelle has called it.
With the US already sending so much money overseas, and now all the terrorism costs -- not to mention the indirect terrorism costs, like giving hundreds of millions to North Korea to entice them to be good, etc. -- how long will it be before the US collapses the way the Soviet Union did?!

However this is going to be exciting, even if it does mean fighting our way up from the bottom.
