Some government programs need eliminating; they are ALL pork and unconstitutional as well.
Defense and Intelligence have already been cut disastrously low, while urban vote buying (AKA "welfare") has dramatically increased over the last 3 years.
Even with a FY 2007 level budget, the United States will still spend more on defense than the next 17 nations combined, most of whom are our allies, and three times more than the Chinese. We would still have more ships than the next 11 navies in the world combined, more manned and unmanned aircraft than any other nation, and a total ground force (active duty and reserve) of 1.5 million highly-trained people.
