Will sequestration undermine U.S. national security? Hardly. Today, the Cato Institute released a new infographic putting these minor cuts in perspective.

Military spending will remain at roughly 2006 levels—$603 billion, higher than peak U.S. spending during the Cold War. Meanwhile, we live in a safer world. The Soviet Union has been dead for more than two decades; no other nation, or combination of nations, has emerged since that can pose a comparable threat. We should have a defense budget that reflects this reality.

To be clear, sequestration was no one’s first choice. But the alternative—ever-increasing military spending detached from a legitimate debate over strategy—is worse. We should have had such a debate, one over the roles and missions of the U.S. military, long before this day of reckoning. And politicians could have pursued serious proposals to prudently reduce military spending. Instead, they chose the easy way out, avoiding difficult decisions that would have allowed for smarter cuts.

Until now, there have been few constraints on Washington’s ability to spend what it pleases on the military. As my colleagues Benjamin Friedman and Justin Logan put it, Americans “buy defense like rich people shop, ignoring the balances of costs and benefits.”

Policymakers can’t postpone the tradeoffs forever, especially when the public has grown increasingly weary of foreign entanglements. If forced to choose between higher taxes, less military spending, or lower domestic spending, in order to balance the budget, the military fares least well, with solid pluralities favoring cuts in military spending over cuts in other programs.

Which is why it is so important to get the foreign policy debate right. If we are going to give our military less, we need to think about asking it to do less.

A number of experts have done that, rethinking the military’s purpose, and documenting the savings that would flow from a more modest foreign policy. The sequester is a first step, albeit an imperfect one, that could finally compel policymakers to do the same.
