I know a LOT of people that either enlisted or (like myself) attempted to enlist and were refused for medical reasons. NOT ONE went because they were eager to fight or wanted an excuse to kill something. Many chose the military because they felt the country was in danger and decided that somebody had to shoulder the burden of facing that danger. Others went out of family tradition, or because it was an opportunity to gain skills and traineng that are expensive or difficult to acquire on the civilian market. Some decided that a soldier or a sailor had an opportunity to travel that no civilian could equal. Not to mention that the last thing an army (any army) wants to do is had rifles to bloodthirsty psychopaths - they're a liability in combat and lose wars.
The other major point that I got from what I could stomach of that idiotic article is that it has been proven time and again that a volunteer military is more capable and more reliable than a purely conscript force, which is why the active duty component of most modern militaries is made up of folks that freely chose to stay in - even in those nations that have conscription, most people do their two or four years and go home, with only those who choose to stay (no different from a volunteer military) making up the bulk of the service in peacetime. Even those forces which the author claims "prove" the superiority of the draft -the US forces in the ACW, WWI, WWII, and Korea- used the draft only to boost manpower - the core of the military was volunteers.
The only conflict in US history that was fought by a purely conscript force was the Vietnam War - the only war in US history that was an unquestionable defeat (the War of 1812 ended with the US gaining every single one of their stated ambitions, and is considered a defeat only because of the notion that it was all a ploy to get Canada) and that defeat was caused as much by the conduct of the draftees (drug use was extremely common, it was almost impossible in many -even most- units to maintain discipline, and they found it far too easy to let essential but unpleasant tasks such as patrolling or entrenchment slide) as it was the poor strategy and political errors.
I can see good arguments for reinstating the draft, but absolutely none for getting rid of the volunteer military.
