It's not like they'll be fighting it out toe-to-toe with swords and spears. Anyway most defense spending waste is going to the large contractors (used to work for one of those), and while that does provide a number of high paying jobs those dollars and the smart people being paid with them could be doing a number of other, perhaps more useful, things for the nation and the world of which it is a part. A lot of them do already, as that engineering talent base fueled the growth of the medical device industry (worked for one of those, too) which, while often owned by corrupt pharmaceutical companies is still a step up from building bombs.
