It's been building for a long time; it's not recent per se, just accelerated.
2025 showed that you can't just go "ok, it's over now, we'll go back to business as usual" (like I know the limp-wristed Dems will want to do) or it'll repeat after every other election until it's successful. You just cannot have this many people constantly being convinced they live in this alternate reality for much longer without civilization collapse.
But I think it's gone too far and we're witnessing the fall of the empire in real-time. I'm just hoping that fall won't screw up the rest of the world too much, but I'm pretty sure it will.
More to the point, it's the collapse of the carefully balanced entente around things like WMD and war crimes that will be our undoing.
Recent events have brought this into sharp focus.
This is really the glue that holds it all together -- that we and our allies haven't even had to think about these things for our entire lives up until now.
I hate to be hyperbolic, but I fear that fear of these things will soon become a looming presence in our lives. For the rest of our lives. And kids' lives. And grandkids' lives.
