You mean the Green party was undermined by Russians?
The Green party had the goal of de-nuclearization from the beginning, at that time the Soviet Union was still in existence. When the Green party came to power and negotiated the nuclear exit, they did not need any external motivation to do so.
The only way I can see this being Russian meddling would be the Green party being infiltrated from Russia from the beginning.
If you have sources that point to the Green party being undermined by Soviet/Russian espionage or some such, please point me torwards them.
The opposite. The (unsubstantiated and probably false) claim is that the Green party was helped or funded by Russian energy companies, who benefited by Germany shutting down its nuclear plants.
Not sure why you're blaming the Greens here, they're a second-tier party in Germany and weren't even a part of the governing coalition during Fukushima and the decision to completely exit nuclear.
The Green party and the Social Democrats were the governing coalition that enacted the nuclear exit. Sure, it was completed by the other two big parties after Fukushima, but by that time the exit was already underway in practice.
