Tucker confuses the hell out of me. He was nice when talking about domestic issues regarding corruption in politics, immigration, infrastructure and so on, then gradually started to decide he was an expert on Eastern Europe while seeming to have zero interest in ever speaking to anyone that might be on the other side of the issues regarding the region. He's ended up shoving himself into a weird echo chamber where he's often repeating what you could read on RussiaToday.
He is still generally OK on those subjects.
Good propaganda is carefully crafted and always comes from a core of truth. Only collapsing states resort to grug propaganda where they bash your head in if you disagree. The fact that he is correct about the border, that he is (largely) correct that the Biden family is deeply corrupt, that the intelligence agencies spy on American citizens quite enthusiastically and so on makes his takes on Ukraine seem more common sense to conservative normies.
It's often what you leave out of the discussion that matters. Or the way you approach the complex issues where everyone involved has a stake, like the Donbas or Gaza. where each side has legitimate concerns.
For example, Glen Greenwald recently moaned about NATO being constructed to limit and oppose Russia. "No, that's demented! It was created to oppose imperial USSR! Which has stopped existing decades ago."
OK Glen, but which state is the successor to the USSR in international law?

So we should remove Russia from its place in the Security Council then?
Crickets, of course.
Or the moaning that the cold war was about communism, which is dead, together with the USSR.
Really, now?
Cold War was about spheres of influence. These ideologies were just a convenient XXth century cover, so we didn't have to acknowledge that Russia, China and the US are empires, and they still compete for influence, wealth and so on. It's so much better if it's about capitalism vs communism, isn't it?
Proven completely false by history and the irrelevance of China and Russia market economies, which did nothing to tame their expansionist appetites.
The real issue is that you cannot talk about any of this shit, anywhere in the mainstream.
If you're pro-Ukraine, you cannot bash liberalism or be openly nationalistic. I mean you can, but then the Western allies will contort into shame when Russia seethes that some dude fought with the Nazis against USSR. If you're pro-Russia, you have your own set of idiotic taboos that you cannot touch upon.
It's all so tiresome. And largely because of these lies, the conflict continues.
