… there’s a second way to look at this. The violent opposition to the Vietnam War and the particular violence of May 4 [, 1970] also played a major role in ending the draft and thus insulated students and young people generally from many of the issues that had spurred such activism in the 1960s. Waging war today is a matter of finding the right price point at which sufficient numbers of young men and women will be tempted to risk their lives in service to their country. Arguably, too, it’s a matter of fostering economic conditions—underpaid and underemployed youth, hyper-expensive higher education—that make military service an attractive choice. What’s apparent, though, is that American troops have been in combat somewhere in the world almost continually since November 2001 with barely a whimper from the campuses that led the opposition to the Vietnam War.
