I have a new piece up at ForeignPolicy.com this morning, commenting on the GOP’s apparent confusion about government spending and the effects that such spending has on others.

The party that opposes nearly all other forms of federal spending happily embraces the military variety. Republicans assert that military spending cuts will result in massive job losses, even as they argue that cuts in other federal spending would grow the economy and create jobs in the private sector. They are skeptical that the federal government should engage in nation-building at home, but celebrate it abroad. Republican candidate Mitt Romney accuses Obama of fostering a “culture of dependency” in the United States, yet ignores that U.S. security guarantees have created an entire class of affluent countries around the world that now rely upon U.S. tax dollars to pay for their defense.

Trouble is, as I point out, President Obama “hasn’t been anxious to kick other countries off the dole.” He boasts that the “the United States is still the world’s ‘indispensable nation,’” and he pledges that the U.S. military will continue “to underwrite global security,” which doesn’t leave much for anyone else’s military to do.

Such an ambitious mission is expensive.

Obama’s unwillingness to make deep cuts in military spending confirms his rhetoric. Over the next decade, the Pentagon’s annual base budget (which excludes most war costs) will average $517 billion in constant 2012 dollars, 11 percent higher than what Americans spent during the George W. Bush years.

For many Republicans, but especially for Mitt Romney, that isn’t nearly enough. They accuse the president of gutting the Pentagon’s budget, and loudly complain about his unwillingness to undo the automatic spending cuts that would cut even more (that they, inconveniently, engineered).

Republicans could reasonably claim that military spending should get a pass because the Constitution clearly stipulates a federal role in defending the country. But nowhere is it written that Americans must provide security for others; that is the job of their governments, not America’s.

Indeed, the Republicans’ reflexive commitment to more military spending is particularly curious given their appreciation for how incentives work in the domestic sphere. Republicans know quite well that people are not inclined to pay for things that others will provide for them. GOP leaders speak often of moral hazards — when individuals or businesses behave irresponsibly because others are there to bail them out. The same problem exists in international politics, but is strangely ignored in the GOP’s plan to continue policing the world.

I conclude the piece with some unsolicited advice for the GOP nominee, but I doubt he’s listening. You can read the whole thing here.
