The Soviets (and I'm sure later the Russians) funded, both directly and indirectly, various anti-nuclear power causes. Saying they were "literally" a Russian funded psy-op is too strong, but the roots of the movement definitely benefited from Soviet funding, as did "peace" groups opposing American nuclear weapons being stationed in Europe.

As far as conspiracies goes, this one pretty much borders on open secret.

> In his first term, Schröder's government decided to phase out nuclear power, fund renewable energies

> Since leaving public office, Schröder has worked for Russian state-owned energy companies, including Nord Stream AG, Rosneft, and Gazprom.

Gerhard Schröder has not worked for russian nuclear reactor companies for a reason.

Not everything is a conspiracy, true.

That said, if something really fits into Russian strategic interests, I'd be surprised if they didn't put their thumbs on the scale somewhere, and propaganda + targeted bribes do have some effect on the population.

Already since Lenin, propaganda directed at intellectuals and politicans abroad was the main weapon of the system. USSR formally ended in 1991, but the people and traditions are still extant and after a 90s hiatus are deployed again. The entire Putin's narrow circle of power are old-school USSR 60+ y.o. spooks, they won't change their ways any more than a tiger his spots.
