Frankly, I'd abolish the draft.
If you mean raise the age requirement to be able to enlist: I'd keep it where it is.
And yeah I know raising or lowering age requirements for voting would trigger arguments like "If I can enlist at 18, why can't I drink beer at 18?"
No just draft age. Agreed if someone wants to enlist at 18, It's their adult choice. But to say you can't vote till x age draft would have to be at that age. Draft is necessary if we have massive issues.
