Waste doesn't defend us. On the contrary, spending too much on the Pentagon just subsidizes bad choices.
The Pentagon's $44 billion Defense Logistics Agency notes that it spent over $7 billion on unneeded equipment. Meanwhile, Congress is doing its part by inserting its own pet projects into the budget, whether or not they are top priorities in terms of defense needs. The most notable example is the F-35 combat aircraft, which at $1.4 trillion over its lifetime is the most expensive weapons project ever undertaken by the Pentagon. Despite the fact that the plane is far from ready for prime time, Congress stuffed 11 additional F-35s into the defense bill that was signed by the president last month.
