Putin has ordered a Soviet-era military base reopened in the Arctic as part of a drive to make the northern coast a global shipping route and secure the region's vast energy resources.

"It only takes 15-16 minutes for U.S. missiles to reach Moscow from the Barents Sea. So should we give away the Arctic? We should on the contrary explore it."

So political leaders -- those in Congress and those vying for the White House -- can generally buck the public on foreign policy without losing votes. It is not that politicians entirely ignore voters’ foreign policy views. But, at least compared with tax and entitlement issues, politicians have considerable rope to pursue their own agendas. Only in rare circumstances, such as very unpopular wars, do voters hold politicians to account on foreign policy.

No state menaces U.S. borders or regularly checks U.S. military actions abroad, as the Soviet Union once did. Trade accords matter a good deal for certain industries, but most of us barely notice them. For the majority of Americans, even the war in Iraq brought little worse than marginally higher tax rates and unsettling TV images. With bigger things to worry about, such as job security and health care, Americans have little incentive to inform themselves about foreign policies; it is rational for them to remain ignorant. 

Realists and other reliable skeptics of intervention are essentially confined to the academy, while true isolationism has become virtually extinct in Washington.
