PGMs

My latest at the National Interest is a broad assessment of the role of PGMs in American grand strategy:

How has the growth of the Precision-Guided Munitions (PGM) complex changed the balance of international power? More specifically, how has the U.S. military’s embrace of this system of weapons affected its ability to accomplish U.S. national goals? The president’s decision to pursue the war against ISIS strictly through the means of airpower and seapower makes the question particularly relevant. The United States will fight ISIS with precision-guided munitions, and apparently little else. It’s worth asking how effective they are in accomplishing national ends. The answer, it turns out, is surprisingly mixed.
