No one who was for blocking nuclear power was doing any long term thinking, I can assure you. That was cold war paranoia thinking that suddenly everyone would be engaging in nuclear warfare. They would have realized we are not ready to transition away from nuclear power because there is no alternative for our power requirements beyond nuclear energy or dirty energy. Long term thinking would realize that the march we are on currently with climate change will also end up looking a lot like a world after nuclear warfare disrupts society.

No, it was short term thinking that has brought on these opinions. Thats who funds these anti nuclear opinions anyway, people who are invested such to benefit in the near term over preventing adoption of nuclear energy, not actual scientists engaging in long term thinking.
