Culling American military bases overseas would also reduce the risk of American politicians capriciously choosing to use those military bases as the staging points for military adventurism; the "War on Terror" was greatly facilitated by those bases. As somebody who thinks that 'war' was a disaster for the interests of average Americans, I would not be sad to see the means for America to wage foreign wars greatly diminished. I simply don't trust the American political system to be a responsible steward of that much global military power.
