I think they were blindsided by how huge of an issue climate change has become. If we had started decades earlier (and the knowledge was there), it might still have been a somewhat comfortable path, even without nuclear. And nuclear does have its problems. I used to be against it, but right now the risk and problems are just not an issue compared to the consequences of carbon emissions.
