I see. The Green movement is globally all powerful, and you explain away the fact that the world is still not a Green utopia by saying the Green movement isn't actually Green. This is awesome mental gymnastics!
The alternate explanation is that nuclear is a sick technology, and the Green movement is not responsible for its failure. Nuclear was so weak even a group as feckless as the Greens could have success against it.
Greenpeace etc have long protested against nuclear, and have boogeymanned their way into the public consciousness on this topic. It's conceivably set us back decades and released millions of extra tons of CO2 in the process.
A classic correlation/causation confusion. Yes, Greenpeace complained about fission. No, that doesn't mean they caused fission's failure.
If there's many billions of dollars in value to be created, that will trump anything a NGO can whine about. That's why we're still burning so much fossil fuel. Nuclear was vulnerable because it wasn't creating value.
