The 50s happened after ww2, the 60's happened cause of Nam, and the 70s were insane from overspill.
The next decade is gonna be a riot. It takes time for the generation who is service age to understand how fucked up war is, they generally have historical knowledge of it but no real experience.
Reality is sinking in, pretty soon it will be a damn loud angry opposition but it wont be revolution. It'll be enlightenment. It'll be an embrace of technology and open minded attitudes. It'll be tolerance and acceptance of other peoples personal choices.
