Remember, the youth have protested in the past, and some change has been effected, but let's not get ahead of ourselves. In hindsight, it wasn't the sea change it might have been thought at the time. We didn't get out of Vietnam because of Ohio State. We got out because we lost the war.
Seriously. We could have drawn it out, but we lost the war, and the myth that the military was stabbed in the back by politicians and protestors at home is fashy and incorrect. And the myth that protests moved the needle very much militarily is misguided, based on fashy nonsense, and incorrect. Basically, while public opinion did make some difference, it didn't make all the difference, and student protests were only a small part of that.
I really hate being a history buff because I know this shit and it bums people out.
