of course I am aware of that. the point being that when the war machine is in full gear, nearly anything can happen, and there's no reason to believe it won't happen again.
There's every reason to believe it won't. The modern US military does not need or make use of masses of lightly equipped, poorly trained troops. Maybe if we were at risk of being actually invaded, the draft would come back, but that's not the case, nor do I expect there is even the slightest chance of that happening while you are of draftable age.
