Ah, the draft. A stupid thing if there ever was one.
People do a better job when they want to do that job, not when they have no choice but to do so. I've even heard it called slavery, not that I'd put it down to quite that level - but worthless it is anyway.
Many countries do have mandatory military service for their citizens, I am glad, and proud that the U.S. doesn't currently do this. As I have already stated, the people who will do the best job, are those who are actively seeking that job, I believe very strongly in that. It angers me when people take job that they don't want, and then do a crappy uninspired job because of this - it's even worse when they don't do this out of their own choosing, IMHO.
