Do you think military service should be obligatory?
Absolutely not, and I doubt the military wants it that way either. Who would want soldiers who weren't committed? I wouldn't mind seeing SOME kind of national service strongly encouraged, but not just military, and not obligatory.
I think the way the U.S. has a good way to set it up. You don't have to join, but if you do, you will gain good benefits from it (Post 9/11 G.I. Bill, tax free shopping, etc.).
