The irony is that a primary beneficiary of our "defense" is a certain Communist (in name only, at this point, but that doesn't matter much) country in east Asia.
This problem with radical Islamists could have been solved by cutting off their flow of funds. The bastards derive their power from their oil exports to the West; if we used our own natural resources and refused to give them access to our technology, none of this would have ever been a problem.
That is a GREAT idea! So simple, so elegant, so workable. I would like to see that as the next passed ammendment.
