Andrew Exum thinks Andrew Bacevich should "just own the term 'isolationist' and let the haters hate." Greg

To me the term isolationism has always implied more than just a country's overseas military footprint and willingness to use military force. It encompasses trade, diplomatic engagement, and an openness to immigration, among other things. Just because you think using the military to try and foster a democracy in the Middle East or Central Asia is an improper use of American power doesn't mean you want to pull up the drawbridge and retreat into Fortress America.

Larison agrees. So do I. Prudence is not isolationism. And uni-polar worlds do not last.
