I was there as well, the bush presidency lasted my entire middle and high school career, and I got the chance to vote for Obama in my senior year.

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.

In 2002, there war in Iraq had large popular support, something like 70-80 percent. It took a few years for people to realize it was based on a lie and was a massive mistake. It was also morally reprehensible, but that part is not often discussed in mainstream US politics.

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.
