All this neither having the dates right nor making a logical Russian gas connection. It's just a pure hate on Germany bs argument which appears all the time nuclear is the topic.
But why shutdown nuclear? Yes the decision might be made in 2002, and exacerbated in 2011. The question is still not answered.
Why shutdown nuclear? Why do you have to ask me that question when you've been ready to form such a strong opinion in the first place? Did you do no research? Didn't you at least look at the wikipedia article? Something about waste, not needing it, being expensive tech from the last century? Nothing of that came along in your research? No? The single thing that you got from your sources was: "something something Fukushima"? Didn't you at least question this at some point? Because I question your abilities to form an educated opinion here.
Germany had a plan to get out of nuclear energy already in 2002
When Angela Merkel came into power, she rolled a part of it back. Allowing for some of the plants to run longer.
After Fukushima, this was rolled back again.
