I haven’t seen that excerpt but I guess the question is it intentional deceit (track record makes that highly possible) or is it confirmation bias (which people, including the media, are highly susceptible too.
The way Russian propaganda tends to work is they take a standpoint that in effects benefits the Russian stance, and then amplify it. There is a real stance- held by some on the right and some on the progressive left that says why are we spending billions of dollars on a country we don’t care about when we have XYZ problems in our country and look at what happened in Afghanistan, Iraq, and Vietnam. Do I think this is a smart viewpoint- absolutely not. But I understand why people might have that (IMO superficial) viewpoint.
Some/many who oppose the anti-viewpoint whine that this is Russian propaganda. In most cases I don’t think this is the case. I think that’s a highly dismissive view. Again, it’s well known the Russians will amplify those that in effect support their cause. Our media does the exact same thing with our own domestic issues.
I don’t think calling this Russian propaganda is an effective way of challenging this- even if it is. Especially given how Russiagate ended up- or at least in the mind of the Trump supporters. It makes a hell of a lot more sense to actually argue why supporting Ukraine is worthwhile than demonizing those that oppose it. You might be able to change a few opinions that way, but that’s not how you effectively influence people.
