Military Budgets

Looming budgetary constraints and the U.S. Army's ongoing downsizing have enhanced the appeal of forces that are lighter, smaller, and cheaper than tanks and other protected vehicles. But not only have armored forces proved critical in yesterday's wars; they will also be needed to win tomorrow's.

With the rise of endless irregular wars playing out in the shadows, special operations have never been more important to U.S. national security. But policymakers and commanders focus too much on dramatic raids and high-tech drone strikes. They need to pay more attention to an even more important task these forces take on: training foreign troops.

Some have questioned the value and effectiveness of MRAPs. But data from the battlefield and the results of extensive live-fire tests demonstrate that, compared to up-armored Humvees, the new combat vehicles save a significant number of lives and, as a result, are worth the cost.

Given the threats it faces, from nuclear-armed autocracies to terrorists, the United States cannot afford to scale back its military, argues Paul Miller. Micah Zenko and Michael Cohen reply that the danger of these challenges is vastly exaggerated and that an overly militarized foreign policy has not made the country safer.
