The phase out of nuclear had already started. Merkel reversed that, than in the wake of Fukushima reversed that once again, paying the nuclear companies hundreds of millions of damages in the process.
The Nord Stream pipeline was completed in 2011, the same year Merkel decided to accelerate the phase out of nuclear. The US had repeatedly warned against constructing the pipeline because of energy dependence on Russia.
Everyone knew that apart from coal Germany has no energy resources. Given that it wouldn't be possible to meet climate goals with coal the energy would need to come from either the newly constructed pipeline or renewables.
That the newly created energy dependence would give power to dictatorships may not have been at the forefront of the public's mind. But treating it as something unknowable without hindsight lets the politicians who caused this travesty off too easy. If Merkel had been honest to the public about the potential consequences of her decision, perhaps it would've been a part of the debate.
