Personally, I have always felt that the most logical explanation for the baffling German behaviour in the first few months of this war, but also in the past 20 years regarding Russia... well the most logical explanation for me is that there is deep corruption in the German State, that Russian money has influenced key German politicians, either directly or indirectly. I have no proof, and other posters told me I am wrong, which is quite possible, I have been wrong in many things in the past, perhaps the underlying reason is not corruption but just "miscalculation"... but I am not sure...

The pipeline was a priority for Moscow and Berlin alike, with German officials from both major parties acting as eager cheerleaders.

Mr. Sellering and his successor as governor, Manuela Schwesig, were allies of former Chancellor Gerhard Schröder, a fellow Social Democrat, personal friend of President Vladimir V. Putin of Russia and lobbyist for Russian energy companies.
Mr. Schröder’s conservative successor, Angela Merkel, whose constituency was in Mecklenburg-West Pomerania, approved Nord Stream 2 after Russia’s 2014 invasion of Crimea, and defended it even after Moscow hacked the German Parliament, assassinated a Chechen rebel in central Berlin and poisoned the Russian dissident Alexei Navalny.
Before the war, the current chancellor, Olaf Scholz, called Nord Stream 2 a “private-sector project” and last year, when he was finance minister, he personally wrote to his U.S. counterpart to demand a stop to sanctions. (In October, Mr. Scholz claimed that he “was always sure” that Mr. Putin would “use energy supplies as a weapon.”)
