A two year stint of slavery isn't going to instill love of one's country with young people. Oh, quite the opposite. It will instill deap seated hatred of a government that tells them they're free one minute and then enslaves them the next.
It would be the source of many, many riots. And rightly so.
So whats wrong with that?
Your ignorance is breathtaking. There's a hugh difference between serving your country and slavery for cryin' out loud.
I live in the homeport community that is proud to have the opportunity to host the aircraft carrier Abraham Lincoln. I see daily the benefits of military service. The work and other opportunities offered to the enlistee's and draftee's too if it were so, cannot be described in anyway as slavish.
There's other ways a person could serve their Country too and none of it requires being subjugated. Consider the words; Honor Duty Country.
Using your logic concerning a draft, then compulsory education is slavery.
