I saw interviews with young Americans on spring break and they were so utterly uninformed it was mind-blowing. Their priorities are getting drunk and getting laid while their country bombs a nation “into the stone ages”, according to their president. And it’s not their fault: they are the product of a media environment and education system designed for exactly this outcome.
Trump doesn't have to justify a single thing because the billionaires behind him know that every last bet is off and their very livelihoods are at risk, and his entire base of support up and down the chain are either complicit or fooled.
What the world does when they finally realize Democrats and Republicans are simply two sides of the vast apparatus suppressing the will of the people by any means necessary will be... spectacular.
I remember things very differently. Everyone cared about the Iraq war, gay-straight alliance was one of the most up and coming clubs, and political music was everywhere. Green Day had their big second wave with American Idiot, System Of A Down was on top of the world, Rock Against Bush was huge, anarcho-punk like Rise Against was getting big.
I'm not a teenager anymore obviously, so it's entirely possible I'm just missing it, but I've seen very little that compares to those sort of movements. On the other hand, most millennials I know are still wildly politically active.
If you compare that to the current Iran war, a majority of the population is already against it, however the current administration doesn't seem to care much about public opinion, and there doesn't seem to be much that the public can do about it.
