The conservative CDU is responsible for the decommissioning of nuclear plants
This is a lie.
The atomaustieg was decided by the SPD+Green coalition in 1998 as a condition for the Green joining Schroeders coalition.
The CDU actually reversed course just before Fukushima but unfortunately Merkel then undid that to try to win voters away from the greens by joining the fearmongering post-fukushima.
the Greens extended the lifetime of the remaining plants
By 3 months, under enormous pressure from all sides during the worst energy crisis in postwar german history when they could have reversed course or extended them longer. You don't get much credit for this.
This was inarguably one of the greatest political mistakes of the 21st century so far and the blame is squarely on the Green party and their voters. The real propaganda is you trying to deflect it into the CDU.
