While I have no doubt that the Defense Department wastes a whole bunch of money, I do think a strong defense is one of the few things the government spends money on that is Constitutionally justified. As super powers rise and fall--the USSR no longer is one but China has become one--I don't have any doubt in the world our ability to wreck absolute havoc on our enemies is the only thing that has given the American people relatively unparalelled assurance that we won't have missiles and bombs raining down on our neighborhoods and we really don't have concern that anybody will attack us.
And we have a President who finally takes international terrorism as a real and present danger for U.S. citizens and isn't concerned about being politically correct so that he ties our hands to deal with it. And because of him, we are less worried about terrorist attacks and even places like Europe have significantly fewer attacks these days though the danger still exists and we need continuous and efficient monitoring and interception of all threats.
Through the efficient intelligence of the USA, Israel, and Saudi Arabia of all places, an unnamed but large number of terrorist attacks have been averted here as well as in Europe.
