I would suppose so, if you see a relatively big organization promoting things that you want to happen why wouldn't you finance them?

That Russia would finance the Greens doesn't automatically what the Greens advocate for wrong, or that the Greens are actually traitors, what it does is twofold - start a process whereby the Greens can over time be corrupted (via the money spout), and indicate that whatever the Greens are doing there may be unintended side effects which would be of benefit to Russia.

Greens are not financed by Russia, this is publicly available information. Neither they did anything that could look like a support of Russian agenda.

anti-nuclear is pro-fossil. I'm saying that russian psy-ops organize both sides of protesting factions in e.g. Qanon, yellow vests in France, etc. - why wouldn't they covertly finance anti-nuclear if they overtly finance pro-fossil? Greens are pro-environment, but don't offer substitute energy sources (because it isn't possible to offer them, a different discussion) - exactly the kind of turmoil Russia thrives in. but then, maybe the FSB's just lucky here.

> anti-nuclear is pro-fossil

Wrong and baseless. It is possible to simultaneously reduce nuclear and fossil components in the energy balance and this is exactly what is happening.

> why wouldn't they covertly finance anti-nuclear if they overtly finance pro-fossil?

Greens in Germany are established political party with clear anti-Putin positioning. Financing of political parties in Germany is transparent and has sufficient oversight, so there’s neither possibility nor any sense to covertly finance them.

Where did you get that from?
