Personally I think that military service should be a prerequisite to have the right to vote....to have some skin in the game. Option 1, Any and all well bodied high school grads should be made to serve for 2 years...no exceptions no exemptions other than physical disabilities, and those with some type of handicap that was not completely disabling should be made to do 2 years of civil service compatible with their physical abilities....or option 2...give up their right to vote.
I would never support either of my sons volunteering for service..but a draft is another story. A draft would guarantee that the Military had the first shot at the best and the brightest.
What if they have a bone spur in one of their feet, but can still play competitive football?
