Well, a draft would certainly make the public aware that we are fighting 3 wars simultaneously. One wonders if these wars would be so lengthy if the draft was reinstated 10 years ago.
Would students in college be protesting and the press show highlights every night on the television? I think the different demographics from a draft would be good. I think I read where the southern states supply more then their share of troops. I don't know if that is because of poverty or patriotism.
My answer would be that I think every citizen should serve this country in some sort of capacity.
