Imagine if Dubya's daughter(s?)
were assigned to a MASH unit that would be sent to Iraq... Think we'd be preparing for war?
If the draft were re-established, IMHO, it should be run like the Nam lottery. But this time with NO exemptions. (Students enrolled in a ROTC program would be deferred until they completed the program or dropped out of the program. We still would need to have trained ossifers. :)) Let the Service doctors decide who is medically unfit for duty. And include women. There are enough non-combatant jobs within the military for women to fill. (Though I'd like to see the restrictions against women being in combat positions removed.)
The cost for the military would not change. Instead of being staffed with only volunteers, we'd have a cross section of the American population. Of course, if the number of bodies needed increased, so would the cost...
Not sure about "Universal Service". I saw it in action while living in Germany. I do think it's would be a good thing, but not sure if the American public is willing to accept that idea. (Why, they still won't accept universal health coverage...)
One last point... Make the period of service the same as during Nam... 2 years active + 4 years inactive.
