1) the US Military is a professional, all volunteer force. Reinstating the draft would cause numerous morale issues.

2) It takes an average of two years to train and integrate a soldier into a unit from the time they start basic training. The normal draft term is two years. This would help us how?

3) The modern military is not the military of the past. An infantry soldier no longer just needs to learn how to shoot and move on the battlefield. Infantry soldiers now operate high tech equipment that takes time to train and become proficient on, unlike the vietnam era draftees. Again, it takes an average of two years for a soldier to become completely proficient and integrated into a unit, and that time is for a volunteer soldier who wants to be there. I shudder to think how long it would take to accomplish the same with an unwilling draftee.

The draft is not going to happen.
