How about the Allen daughters? /s
It's probably not realistic to expect anyone to sign up. What should have happened on 9-12 was for a Universal Service Bill to be place on the President's desk. It would have included a draft and it would have included women.
Interesting view of military service. The current circumstances haven't prevented hundreds of thousands from volunteering over the last few years, to include the sons of Duncan Huner and John McCain. Military service should be something every American young man attempts. With five active services and their reserve components there is really no reason a physically (and otherwise qualified) young man ought not attempt to join.
As regards drafting women, what would be the point if we are drafting all the men we need? If anything, conscription would allow the military to raise standards and eliminate double standards in place to accomodate females. The Army and probably the rest of the services would be able to bring their percentage of females serving back down the the pre-1973 levels.
