Maybe he should stay with playing war and leave the real stuff to the professionals. Logistically speaking it ain't that easy. Can we do it? Sure. But it ain't going to be Afghanistan.
Don't be too quick to dismiss war "gaming". Some of it is for real. In spite of the name, the military does a lot of it at the leadership level, and it is no "game". Think of it as extensive scenario testing prior to starting the real thing.
Don't know about this guy specifically, although he seems to be both informed and connected.
