On the late great two-war strategy: For years the United States has claimed it is capable of simultaneously fighting two full-fledged wars in two parts of the world. The Iraq War has proven that claim false. We've had our hands full fighting and supplying one war against an impoverished country that can barely fight back -- and our struggling economy will have to sacrifice school lunches and veterans' benefits, among other things, to manage that. In addition, our reliance on air power is draining our capabilities. One example (The New York Times, April 2): Merrill A. McPeak, former Air Force chief of staff, said "We are relying to a great extent on cruise missiles, of which we have a limited supply." If India-Pakistan, or North Korea, or any other major trouble spot, decide to misbehave, our military options would be severely limited -- and now they know it. In addition, major governments who've supported Bush (England, Spain, Australia, Italy, Jordan) are reaping severe domestic consequences; such governments may not be eager to join Bush again. Which may mean: Iraq could backfire and, in the long term, weaken the U.S. deterrent. Not only our strengths but our limits have been demonstrated for all the world to examine.
