This past Monday I wrote about proxy wars, what they are, etc. Today pops up a new article in Le Monde Diplomatique (English edition) which details the many, many proxy operations the U.S. is involved in around the world. Hat tip to RealClearWorld for the link.
If the article is to be believed, proxy war is the preferred military model of the 21st century. You'll note that the article's author is less-than-convinced of their usefulness.
