I love Kraftwerk, but contributing to anti-nuclear sentiment in Germany hasn't been a major success. If only more European countries had followed the French example and developed substantial nuclear fleets.
coal kills more people, this is a fact. so with blocking nuclear lead to coal, so they indirectly supportered killing thousands, incredible stats really. who said art can't be bad for the public?
Like most backward looking judgements these days, such things require understanding the culture and zeitgeist of the mid 70s.
I'm pro-nuclear as well, but understand that for many decades the "smart" thing to do was to oppose it. I wouldn't expect a musical artist to have a more nuanced opinion than most of their contemporaries.
