yeah, probably.
it's general principle behind why the marines are more elite than the army (boom, pat): you've got a bunch of guys that absolutely, positively want to be there and money has very little or nothing to do with it. there are no gigantic bonuses, no massive tuition assistance, no 2 year contracts -- just a bunch of hard, redneck SOBs that are there because they love their country and they want to protect it at any cost. if you start adding in a bunch of malcontents that would rather be playing xbox, you're diluting the force.
so while, to me, draft vs. national service initiative isn't necessarily a tough question, the ability to steer able-bodied young men towards the armed forces would still be somewhat of an issue with any national service initiative. i think that comes down to education, though; outright propaganda probably isn't the most effective way to do it, but somehow, our country needs to do something to make its citizens proud of it again.
