This ain't the 60s or the 90s. Dead and buried. The only way to revive the war protest movement is a disastrous war ala Vietnam - plenty of bodies going back in coffins - thousands upon thousands. Not the type of modern battlefield the Americans have engaged in - costly $$$ but low on lives. Home stays happy. They've learned their lesson, whether cheap propaganda always drums up the opposite in "resistance circles".
The climate change movement is well, as it always was, full of smoke and mirrors - easily manipulated, hijacked and dissipated. It would take the end of times for it to be a serious political factor in the U.S.
The competition between big rivals will continue at its pace.
