Military Drinking Age

In the Mid 80's, in response to lobbying by Mothers Against Drunk Drivers (MADD), Congress amended the United States Code, Title 10, Section 2683 to require military installations to comply with local state laws in regard to drinking age.

Prior to this, all active duty military personnel were allow to purchase, possess, and consume alcohol on military installations. The thought was "old enough to die for your country, old enough to drink."

Should Congress consider changing the law again, to allow all active duty personnel to drink on military installations?
