Why?

...Once again, Berlin is now tempted to go it alone, as soaring gas and electricity prices are sending its economic and political decision-makers into a tailspin. 

Nothing is crystal clear in the Nord Stream 1 and 2 pipeline sabotage

During the due diligence of the project, practically only environmental issues were considered as elements of utmost importance, dismissing geopolitical considerations, error of errors, and taking into consideration the strategic location of the pipelines.   

The due diligence conclusions failed—first, a terrorist attack on the pipeline facilities. And secondly, because of the pipeline explosion, the creation of an uncontrollable artificial geyser from the natural gas leak in the middle of the already heavily polluted Baltic Sea created an enormous environmental crisis.

Germany and Russia are responsible for the security and maintenance of the pipeline. 

Within the basic routines of natural gas pipelines, apart from using electronic devices for fault detection (fiber optics). Physical inspections (buried, underwater, or aerial) along the pipeline are a must, at least in the critical sections. We are talking about "only" 1200 km long; if we divide this distance by 3, it is 400 km long, equaling nothing to perform its daily route. Had this essential routine been implemented, would the strange ships locate days before in the denotation zones by satellite images have been detected? What is the last straw, that German companies built the pipeline mainly? Nothing wrong? The maintenance of the pipeline was in charge of a German company.

Now that the pipeline has been destroyed. Germany is going it alone... In bad fellowship, every man for himself.
