Like we knew the adults on the planet weren't really adulting, it might cost the world its existence, & there was nothing we could do to stop it because we were just children.
I remember seeing stories on the news about the pro-democracy movements in Eastern Bloc nations, but I didn't really grasp the details.
& of course, it wasn't really 'all of a sudden', it took months & years of pushback & protest & pressures of all kinds to finally bring the USSR down.
The Berlin Wall coming down tho', that was one of those pinnacle moments, a singular point in time at which everything pivoted. We watched in real time as an entire nation *fell*.
It isn't that ppl in the US hadn't turned on one another: of course we have. So many of our internal problems, then & now, are about conflict between different groups: racism, sexism, classism, etc. But for decades, we had an *external* enemy that politicians could use to 'unite' us: 'we're Americans & they're not'.
This is all very broad & general & I don't actually know if I'm right or not, I'm just spitballin' here.
