What hindsight? Everyone knew at the time that it was premature. It was a deliberate choice to bear the burden of increased pollution and to make the country more dependent on the whims of a foreign dictator, because nuclear bad.
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.
You do realize that Germany is not allowed to do any uranium enrichment or waste processing? All of this was outsourced, partially to France, but primarily to Russia.
How is that not "dependent on the whims of a foreign dictator"
Started? The anti-nuclear movement has been around since the 70s.
