By effectively ending the draft it removed many young people’s connection to world events.

I don't buy that theory, as the broader global economic forces were a bigger influence on GenX / Millennial youth than any particular US military hot zone. And I loathe to think how the Bush/Obama admins would have responded to Afghanistan/Iraq if they thought they had unlimited free conscripts to throw at the problem forever, rather than a depleted reserve of voluntary enlistees and national guard troops to draw from.

If all those years of stop-losses and quadruple deployments had instead been years of drafting young people, a lot more people would have stood up the the Bush administration.

I don't think Bush could have been meaningfully less popular with youth voters by 2004. His approval rating was already under 40% in the 18-24 demographic. Young people were regularly in the streets in protest all through 03-04. I was in college at the time, and there were parades of protesters running through the quad at the start of every term. But it was the Boomer voters who dictated the direction of the country, and their hatred of brown skinned foreigners was matched only slightly by their disgust towards Millennials.

The groundswell of opposition to Bush kept piling up until it fully materialized in the 2009 Dem super majority, but then... Obama didn't get us out of Iraq. Hell, the reason he beat Hillary was because he came out as staunchly against Iraq while she waffled. The antiwar movement was widespread in 2008 and continued to truck on through 2012. But it wasn't voluntary enlistment that strangled the war. It was a big wave of ostensibly antiwar Democrats taking office and then not ending it.
