Conservatives who are sincerely supportive of all Americans’ freedoms and see our military for what it really is probably do think it is a bit bloated. However, most Conservatives (admittedly, most Liberals as well) don’t really give a lot of thought to why they should/shouldn’t hold/not hold certain views, they just go with the flow (of their particular ideology).
The naive conservative supports our military because:
They are protecting our freedoms (without really questioning how our freedoms are protected by bombing brown people thousands of miles away).
They are patriotic (ignoring that fact that many civilians are just as patriotic or even more patriotic, dissent is REALLY frowned upon in the ranks, but sometimes dissent is the most patriotic course of action).
They are “real Americans” (for obvious and mostly valid reasons, the services stress uniformity, many people conflate uniformity with integration into society).
They are in harm’s way (getting blown up “for your country” is just so sexy, nevermind that construction workers, miners, commercial fishermen and roughnecks do a job that is much more likely to kill them. They still won’t get a 21 gun salute at their funeral).
It just seem “right” to support our troops and the military as a whole. Few Americans care to examine the cynical reasons that big business, the military-industrial complex and the government have for perpetuating a view that the military deserves some special status and reverence. It’s just a job. Not the best paying job. Not the toughest job. Not the most dangerous job. Definately not the most selective employer.
I’ve been there, done that, spent the GI Bill, but all-in-all . . . I’m just not that impressed. No offense to our troops, SOME of whom are real heroes. But, we have heroes who are accountants, cops, computer programmers, waitresses and lawyers. Most people in those trades are not heroes, just as most GIs aren’t heros. Most people, military or civilian, are just doing a job.
