Another aspect on this thread might be to consider a bit more deeply, what we're hearing from our media and politicians. Anyone who has seen or heard clips of what the Russian media is saying will know that their people are being told a completely different story, which "the West" is saying is propaganda.
Now I'm not disputing that, and I think the Russian people should be entitled to hear whatever they want to. The fact that their Government is cutting off their people's access to stories as told by the West certainly smacks of having something to hide, such as the Russian army doing many disgraceful things and Putin being unreasonable in many ways.
BUT ... when the USA went into Iraq around 20 years ago, there were many demonstrations in many places, but the USA didn't listen or care, just as Putin doesn't care about demonstrations now. And wasn't the main motivation to go into Iraq because they were desperate for a scapegoat for 9/11, rather than because Saddam Hussein was actually intending to send nuclear bombs to America? But many of us listened to the USA then, and as a country we were far, far less outraged by those American actions than we are by today's Russian actions.
What I'm saying is that while I'm certainly against the war in Ukraine and I despise almost everything that Putin is doing, I do think "the West" isn't exactly whiter than white on this, and rather than taking the view that Putin is completely wrong in everything he does as our media tends to portray, we should at least listen to what he says. Then condemn him by all means if you still think it's justified, but at least make some attempt to consider his arguments first. After all, I think many of us were somewhat hoodwinked by Bush when he invaded Iraq.
