The military is still downsizing so, a draft in the near future is unlikely. Currently, the number of people looking to enter the military is such that the military is raising the bar in their requirements. I was a Fire Control Tech maintaining surface and air action radar systems and their peripheral equipment. A HS diploma was all that was needed to get into that rating when I entered the service. Today, the same rating demands an associates degree or higher to get your foot in the door.
Add to the number of military entrants those that are having a difficult time securing employment in the current economy and the inevitability of a draft needed to fill the ranks becomes even more remote.
