Although the first responsibility of any government-including the U.S. government-is to protect its people, U.S. taxpayer dollars are being used to promote overseas empire at the expense of citizens' security. Traditionally, "threats" from abroad were used to plan U.S. military forces and the strategy used to employ them. After the Cold War ended, however, this approach went out of favor because most of the threats evaporated. The continuation of massive U.S. defense budgets-U.S. expenditures for national defense are equivalent to the total defense budgets of at least the next 13 highest spending nations combined-had to be justified by some other means. So the Pentagon moved to "capabilities-based" planning. This slogan merely means that new weapons technology can be developed and existing weapons can continue to be purchased, even though no threat exists for them to counter.

For example, the stealth F/A-22 fighter, the first squadron of which just recently became operational, was designed to counter Soviet fighters that were never built. Now the main threat to U.S. fighter aircraft is not aircraft from other nations, but ground-based surface-to-air missiles that can be avoided by flying around them. This program should have been terminated long ago but is kept alive because it provides jobs in many congressional districts across the country. Similarly, the U.S. is building new classes of CVN-21 aircraft carriers, Virginia-class submarines and DD(X) destroyers when the threat from other naval powers is negligible. Yet the QDR eliminates none of these unneeded or Cold War weapon systems, although the DoD has more weapons on the books than it can pay for even with its massive budget.

The 9/11 attacks and the subsequent amorphous and unending "war on terror" have allowed the Pentagon to justify higher defense budgets-including the aforementioned weapons not suited to fighting terrorists or guerrillas-to a security-conscious public for the indefinite future. Yet such adversaries can be best fought with infantry, special forces, and existing aircraft. The United States certainly does not need to spend $11 billion a year on only a minimal defense against attack from nuclear-armed ballistic missiles. The more likely threat is terrorists smuggling a nuclear weapon into a port on a ship, rather than launching it on a missile that they don't have the technology to develop. In the QDR, the DoD promises to make homeland defense a greater priority. But according to Lawrence Korb, a former assistant secretary of defense, the reality is that the Pentagon spends more on missile defense than the Coast Guard, which combats more likely threats.

Even military systems that could be used in fighting terrorists and guerillas need to be effective and cost efficient. The Marine Corps' V-22 tilt-rotor aircraft-which takes off and lands like a helicopter, but flies like a fixed wing propeller plane-has had development problems, including many crashes, and significant cost overruns. Although the aircraft would be good for hauling Marines fighting terrorists or guerillas into remote areas with no airfields, the plane should be cancelled because of its exorbitant costs and meager advantages over existing helicopters.

Because of the Pentagon's capabilities-based approach, the QDR fails to assign priorities to the few remaining threats. For example, what should be the highest priority for scarce resources: countering the threat from al Qaeda, the potential threat from an Iran or North Korea with nuclear weapons, or the possible threat from a rising great power-such as China or India?
