Tom, your timeline is off
<Another 20 years of Unmanned Remote Piloted technology, and EVERY American's going to be watching the war on a television screen, including the soldiers.
I'd bet a few bucks it's going to happen sooner than that.
Except; sooner or later there will have to be feet on the ground. Some poor schmuck is going to have to walk the dirt and chew some rocks to make sure the ROV's did their job. I doubt that is going to change for a very long time.
