Ground wars like those in Iraq and Afghanistan, at 13 years the longest in American history, are things of the past. Defense against Chinese cyber-warriors or terrorists in Africa won't require tanks, warplanes or massive armies. That's the theory behind Defense Secretary Chuck Hagel's proposed cuts in the Pentagon budget. But weapons and manpower mean jobs and corporate profits. Every program Hagel wants on the chopping block has a constituency. Is he really proposing to cut to the core or just scratching the surface of a military bigger than all the rest in the world combined?
