Yeah. For me it was the same with everyone cheering for Ukraine wanting to get into Nato and putting it in their Constitution even though it would never happen. And then everyone acting surprised when Russia invades after they said they would for years. It was so predictable that I can't help but assume that it was a deliberate trap set for Russia. Russia is wrong, but it was predictable, inevitable. But everyone was suddenly so gung-ho that possible diplomatic solutions to end this senseless war were not demanded by "the left". Still isn't.
And kinda the same with Israel now, the Oct.7 was a horrible atrocity and war crime but they blatantly lied to make it sound even more horrible in order to dehumanize and justify the war crimes they are committing now. But so many on the left are still screaming death! and the news in my "progressive" country is reporting complete propaganda.
Gen-Z is presumably just as easy to brainwash for total war with the right propaganda. Or maybe they will grow up being more resistant to it.
