Good luck on that Buddy. The people who would be called upon are for the most part, apathetic, selfish, spoiled, out of shape mind numbed cell phone zombies. All by design I might add. Wars are not supposed to be fought by 35 year olds with families. The only reason there isn't a draft is that they would have to draft women and daddy doesn't want his beautiful daughter coming home with only one leg.
WW2 was the single largest event in the history of mankind. I'd bet that in that five year period, they shot off about 10-20% of the world's resources, steel, lumber, petroleum, strategic metals etc. The amount of labor hours is beyond estimating. It will never happen again because it isn't possible given the world situation. Russiawas making 600 T34s a month and that was just PART of their production. These tanks would last about 10 hrs each. If you think that the American public will give up their I Pads, TVs, cars and free time to fight one of these bogus wars again, you are mistaken. If we are invaded, perhaps, but probably not. They would be looking for someone to sue. Vietnam was the last conflict that bears any resemblance to WW2 and it was tiny by comparison. If I sound cynical, I am.
