I am not german so i don’t know either, but Russia doesn’t have enough influence to force people to believe their stories. I believe even people who agree with Putin from a political point of view understand his invasion wasn’t called for. They know Zelensky isn’t a nazi. Even if they buy the story of NATO having expanded too far east they are often not against being in NATO for example. It is interesting there seems to be a difference in how the party leaders treat Russia and how their voters view Russia.

What i think matters most is not what they think but rather how much they care. Their nationalism comes from a need to care for themselves first, it’s a kind of egoism that i think is rooted in a falsely perceived threat (There are no houses/jobs, because foreigners took them. The taxes are too high because there are too many lazy people living off benefits. There is no good healthcare/education because CEO’s earn too much)*. These threats they perceive are much bigger problems, so they can’t afford to worry about that that war in Ukraine. They will say it’s not really our business anyway, we shouldn’t meddle with foreign affairs. Let the Russians deal with this.

* before i get dogpiled, i’m not saying that it isn’t a problem if there is a lack of housing and jobs, there are high taxes and health care and education are unaffordable; my point is they see an enemy that cause these issues intentionally and they need to fight that enemy (foreigners/lazy people/CEO’s).

European far-right are similar to republicans in Russia’s eyes. We cannot know how much money and influence there is between Russia and them but it is clear that they are the side Russia supports. Obviously it is entire possible that a far-right party isn’t financially or otherwise supported by Russia, but even if they are not at all, the party will have a similar views of the world.
