I don't entirely disagree with this angle; but it has a problem that's easily exploited by right-wing, Libertarian groups and resonant parties. It takes, as its core, primal selfishness: that no one without skin in the game gives a damn. This is a very damning statement about human nature. It presumes that people don't, by nature, care about other human beings.
I think the quote by Goebbels is a better fit: Essentially it argues that MOST PEOPLE do not want war... but they can be convinced that war is necessary if they believe themselves to be under attack. THAT is the motivator.
Most people want basic security. Most people have no wish to harm others.
That's why any war-oriented society must also conduct a War on Information... and use all sorts of lies, mind control, and obfuscation to induce in enough citizens, a willingness to "go along."
Obviously most people don't want their children to return home in body bags; and at this point, with the Afghani debacle dragging on 14 years and--as is conditioned into the American psyche (particularly that of males)--no "win" in this war "game," either. (That's a frame that Tom Engelhardt and many of his writers fixate upon.)
I think the really important item missing, and missing from your analysis is how far down the list of priorities TRUTH has been placed.
If a GENUINE investigation followed 911 and if today's thousands of engineers and scientists were given major media time to discuss the obvious false implications of the story of 911; and if REAL footage of all that "collateral damage" of Empire's wars were publicly aired (so that all those "right to life" types whose lives center on protecting fetuses might actually VIEW little children torn apart or left crying in rubble after their mothers and fathers were suddenly killed); and if analysts who were opposed to war had AIR time... a very different public response would not only appear, but blatantly oppose war.
Jeremy Scahill, interviewed on Democracy Now last Friday, I believe it was, stated point blank that "Independent journalism is being criminalized."
IF ONLY "embedded journalists" which is to say sycophants regurgitating the military's "story," are heard and seen... what chance is there for citizens to KNOW what's really going on?
Clapper lies about the full-scale surveillance apparatus, and until Snowden exposed him, who would have known?
The military can claim anything about this latest hospital bombing. Thankfully, Doctors Without Borders are amazing souls with high intelligence and moral backbone to back it up.
It's not just about the draft! In a sense, implementing a draft just continues to justify wars.
