> Germany's failure to manage its national energy needs due to EU "green" policies made it subject to Russian energy dependency.
Germany did not import EU green policies. It was a driver of those.
The offer of cheap energy from Russia combined with the corruption following that, caused German politicians (CDU/SPD) to make a series of mistakes, like expanding energy dependence from Russia without making sure energy needs are covered in times of a crisis (AFD and BSW are making the same mistake, only worse, worshipping the authoritarian & corrupt government of Putin). When Russia was invading the Ukraine, suddenly the Gas storages were not filled anymore - Russia trying to blackmail Germany. Putin influencers like Sarah Wagenknecht denied any Russian plans, just days before the invasion, when already a huge Russian military, ordered by Putin, at the Ukraine border. At the same time the US already warned allies about the Russian plans.
> The US had to literally rescue Germany from itself by blowing up Nordstream
The US did not blow up Nordstream. Actually the US warned their allies of planned attacks. There is zero evidence for US involvement. The Nordstream pipelines were also useless, since they did not transport gas at that time.
