As has been noted several times here, the draft isn't coming back anytime soon. It is simply not normal for a US not involved in a really big war.

But that still leaves the problem, if it is one, of the American populace being disconnected from the military, not the military being disconnected from the American populace. The Americans as a whole can't be forced into reconnecting or sharing the sacrifice or whatever. They have to want to do it. Parts now seem more apt to serve than others, there are regional differences in rates of service and especially class differences in rates of service. Those differences are volitional. If those differences are to lessen no gov policy can do it. It has to be the decision of the people. Some things gov can't do.

The thing that I think is most problematical about the class differences in service is how the elite classes, those that go to the top 105 colleges the ivies especially, those that comprise the GS triple digits, the corporate board members, the media elites etc, don't serve hardly at all. They know nothing practical at all about the military or much about military history. Yet they are the ones who direct the military to go off and make war. And they are the ones who buy the latest tech or managerial fad like the revolution in military affairs. That is a problem, but again, one that gov can't solve.
