Be it Iran or North Korea who we invade next (either of which I'll be excited about, because Iraq was a bad choice), we'll see our troops spread even thinner and possibly an even larger deficit in recruiting. We are already sending a lot of reserve troops directly to Iraq upon their enlistment. I'm not saying a draft will be popular, but there will be that conflict(s) that comes along that makes a draft mathematically necessary. I'm not saying it'll be today or even 10 years from now, but there's no reason to assume that the draft died forever in the 70's.
