I don't like the idea of a military draft for men, let alone women. The reason it was ended in the first place was because it was declared unconstitutional. I don't like the idea of forcing people to fight, and making it hard for anyone who doesn't want to fight to get out of it.
Why doesn't the government make signing up for a Civilian Corps mandatory? Fixing bridges and clearing away brush from burn areas does more of a service to one's country than going overseas to kill people you've never met, and encourages participants to think in constructive, positive terms rather than thinking about death and destruction.
Anyone who genuinely wants to be part of the military will sign up voluntarily. I don't see the need to make it mandatory.
