Since Korea, the American Military's prime adversary has not been enemy combatants. Rather, the primary adversary has been a crumbling American society encouraged, nurtured and brainwashed by the mainstream American media managed by the radical extremists of the 1960's cultural revolution. The radical extremists managed to get most college newspapers "thrown" off campus, where they flourished with spurious funding funneled from America's enemies. As they graduated and moved into the mainstream, they grew like a cancer until they firmly controlled the mainstream media, which they transformed into a radical propaganda ministry. From this unofficial perch as the information overlords for American society, they filtered information and bombarded the masses with radical propaganda transforming masses of Americans into programmed zombies who react to comfort stimuli like man made "droids" with no soul. At some point soldiers may decide put their families ahead of the soulless zombies lead by more soulless politicians. I believe many soldiers are making a tactical retreat protecting their families and letting the front lines approach and consume the soulless zombies. Eventually, when the zombies are slaughtered and their consumption patterns get interrupted in enough calamitous events, the zombies may awaken. Hopefully, it will be in time to make a "last stand" before our destruction.
I might not go this far, but I do think the sentiment you express is largely correct, and it goes towards a point I made above: Perhaps many are questioning their dedication and sacrifice in relation to what they're hearing from those loud voices advocating a certain position in the media, or from what they're seeing in the upper echelons of command, both civilian and military. West Pointers are not stupid people (Army/Navy rivalries aside) . . . they, moreso than others, perhaps, can see the writing on the wall. Maybe they're asking themselves if they should put their lives on the line---for this?
