How Much Military Is Enough?

This article from the January 28, 2013 New Yorker, is one of the very best on the subject of military spending.  It tells the story of the War Department since 1789, the long period of isolationism that lasted until World War II, and newly growing calls for limits to spending and military power projection.  Well worth the read.
