In my opinion, if the military needs to be larger (a questionable point), than it should be "grown" in a rational and organized manner, with recruitment, training and equipment procurement all coming together appropriately. None of the military services have any trouble meeting recruiting goals, and there is no reason to think that this would be significantly different if the goals were to be increased incrementally. The army really didn't need the masses of the untrained and unwilling that it had during the Vietnam Era, many of whom spent only eighteen months or less in uniform (and I served in Vietnam, surrounded by draftees), and today's military has even less need for them.

IMPO, if we had started the current stupidity with some kind of rational plan for ending it we wouldn't be in the fix we are in today, because we would have had an appropriate force structure and a rational force sustainment plan. Returning to a system of military manpower "planning" that was obsolete forty years ago is far more than a step backward.
