Germany has an option to talk with russia to make a deal, so russia reopens the valve... some other forces don't want that.
It is a 101 of economical warfare.
With the closed valve, they have an upper hand at negotiations about gas, especially if the german people get cold and start sharpening the pitchforks for their own (german) politicians... now, even if the germans want to negotiate, there will be no gas until the pipelines are fixed, and it doesn't seem that will happen soon
Nobody believes in their 'repairs' and temporary issues with the pipeline. I really hope it is destroyed.
If they wanted they could reuse the old pipeline that is on land on Polish territory.
BTW. It is not only my suspicion: https://www.politico.com/news/2022/09/28/nord-stream-pipelin...
