On the other hand, once people figure out that they are going off to
fight
these wars basically as a continual sideshow for nationalistic
interests, the recruiting capabilities for
a volunteer army may indeed dry up rapidly, and the strategy of using
the National Guard as regular army
will certainly backfire sooner or later too.

It will certainly weed out the volunteers that only wanted to volunteer for
the free college bucks, and not the possibility that they may have to go
fight somewhere.
