don't be so sure. As I said in the latest poll the Greens were the leading party to win the elections.
Also never underestimate the US puppets ability to self-harm themselves in order to please the US.
Australia is a good example where they threw everything aside to please their Lord the US.
There's a slight difference that could work in China's favour: Germans are german and Germans as a culture are pragmatic and direct, compared to the Anglo australians who believe their own BS and Kool-aid.
Anglo Australians benefit from the US as hegemon, they're not going to throw that out just to become another Germany, whereas German industry will increasingly need Chinese investment and the Chinese market.
And let's assume that the Greens do win, the eg of Pompeo et al being sanctioned would moderate any of the hardliners in any Greens government, but let us also suppose that the Greens are like any of the Greens supporters in any anglo nation: Ivory Tower privileged Elites who don't know what hard work is and want open borders and believe a nation state can be governed like a hippie commune.
They're going to find themselves gridlocked in Parliament and voted out next election, along with any idiot Party that decides to form a coalition government with them.
We saw this happen in Australia when Labor formed a coalition with the Greens and allowed Open Borders and spent more time virtue signalling than actual governance. The result was that Labor has never been able to get into government and allowed a massive swing back to the far right which we now see with the idiot ScoMo and the "Wolverines".
Although, in the case of Germany, i believe a swing back to the centre right Merkel/Schroeder stance would be far more likely.
