We disagree.
Having been drafted myself, then going to OCS, and later assuming a combat command where I served and fought with other drafted, citizen soldiers, I became of the opinion that, just as rank has its responsibilities, so does serving the concept of "freedom".
Arguably, and beyond a shadow of a doubt, "freedom", as we know it in this country, needs to be served in an urgent manner in order to survive. At no time has this been more evident since it's inception.
Who better than its citizens?
I'm sorry, but the Founders would disagree. They viewed a standing national army as one of the great threats to freedom and liberty in this country.
Coups and military dictatorships unfortunately have been the norm throughout history. Caesar was a great Roman and so were his troops, until he crossed the Rubicon.
With the exception of WWII, what example do you have a "freedom needing to be served in an urgent manner" by the military? I would argue, yes freedom needs to be served, but from political resistance by the citizens against a bloated and tyrannical government.
Maybe in a small, homogenous country surrounded by hostile enemies, such as Switzerland or Israel, does conscription work.
This still is the frontier my friend.
