The biggest driving force is of course the Russian regime but Russian people are hardly bystanders. A vast majority of them actively support the invasion which simply cannot be ignored. Of course there are some people who are against it but Russia as a nation is brainwashed so much that I think the only way for them to change is if they fall really hard, like Nazi Germany did. It's not just Putin's war. It's Russia's war.
They are bystanders in the sense they have no influence on events, whether they are cheering or not is irrelevant right now. Some are brainwashed by propaganda, just as British and American civilians are whenever Britain or US invades a foreign land. Many others are too scared to speak out. Either way they aren't to blame for an immoral and illegal war their government is undertaking, nor are they to blame for living in a fascist dictatorship. I'm just very wary of any kind of xenophobia, and it saddens/worries me that otherwise extremely PC people around me are taking about Russian people. There's an old gimp at my work who at least once a day mutters "never trust a Russian" whenever the war is discussed, and occasionally expands to rambling about his Russian ex wife. One of my best friends is the most woke, anti fascist, pro PC person I've encountered and even he is saying things that are offensive without realising the irony (he would usually rebuke me for any kind of joke or comment that could cause offense). The double standards irks me. People are people at the end of the day, soldiers are soldiers, people will be influenced by the news they consume, soldiers will do barbaric stuff in war, regardless of nationality.
I agree on Russia needing a change, but its virtually impossible to overthrow a dictatorial system that has total power. Any change will be slow and gradual. No external source can intervene, the risk of global, nuclear conflict ensures that conversation will never even occur. Drastic civil revolutions aren't possible in the way they were 100+ years ago, because governments have modern weaponry that a crowd of civilians can not overwhelm. I think the only way change is possible is the fact that we have the internet which provides shared information and interaction with the rest of the world, and allows Russian individuals to consume media that hasn't been scripted by the government. This could help enable a slow, steady change towards a more progressive thinking which could lead to gradual political change. But for this to happen I'd like to see a change in the general tone towards Russian civilians. Imagine a Russian teenager, who is conflicted because they have some pride and affiliation with their country but is beginning to be sceptical of the government and media, and they go online seeking Western perspectives, and there's a barrage of anti-Russian sentiment, Russians being called barbaric, news article that act as though major Western powers have never committed war crimes and Russia and Russians are the absolute worst country ever. That just plays into the Russian government's hands - they can say look at the hypocrisy and dishonesty of the west, they hate us, they lie about us, they insult us. It will only serve to create a polemic divide, and influence civilians to the side of the Russian government. I think we should treat/speak about Russian people with empathy, warmth and sympathy - its the only antidote to brainwashing. You can't scream at a cult member that they've been brainwashed, they will reject the idea outright, you need to be patient, open, engaging, understanding and enable them to realise for themselves. This may seem fairly pointless to post on a United forum, but I do think some of the language and discourse on sites like twitter, even BBC, can en masse have a significant influence over time. Spread love not hate, its everybody's duty.
