War today for the US military emphasizes technology and taking few casualties than in the past and calls for a more highly trained and professional soldier than past wars.
You seem to accept the premise that all draftees will somehow be dumb. You can train draftees to be as highly professional as you want. They'd be trained by the same people, with the same equipment, in the same facilities as the enlistees are now.
As I noted in response to another post, a largely conscript Army defeated the German Wehrmacht, which was better trained, equipped and led than anybody we've fought since. A largely conscript Army did damn well in Korea. And we never lost a battle in Viet Nam that wasn't fought in the CBS newsroom.
