I'm not sure what point you're trying to make? Obviously there's a longer history behind the nuclear power opposition (the bit on the Sierra Club in Freakonomics ep 516 is quite interesting), but Fukushima was the trigger that caused the CDU to cave (and Japan's LDP to reverse course). More to the point, they can restart their reactors to both dramatically cut CO2 emissions and to reduce reliance on foreign fossil fuels with minimal lead time.
