Note who these ‘politicians’ are and what their political orientation is…and you will rapidly understand what they (think) they are gaining and why they are scaring the people who are their targets.
The draft is a left wing fantasy used as a club to rally their base and (in theory) ignite even more opposition feelings among the center. Its like the Big Lie™…if you keep telling it long enough it become reality because people THINK its real.
As to what people would do in the highly unlikely event that we had another draft, I’d say they would do what they always do. Some would go, some would resist. The military would gain raw numbers at the cost of effectiveness and cohesion. Overall it would be a lose/lose for the military in the long run. It would take too long to implement the policies, draft the shlubs, train them, get them in theater…and they they would suck as soldiers, being unable to do the highly specialized jobs the military requires (even the combat troops). It would ruin morale as well, with a large percentage of young, resentful people filling the ranks…and forming a separate ‘caste’ from the all volunteers/veterans we currently have.
The military doesn’t want it. Afaik Bush et al don’t want it. The Dems who have actually brought it up don’t REALLY want it…they just want to use it like a hammer to frighten the wide eyed crowd.
