> It’s only expensive and brittle because environmentalists have choked it to death How did they succeed with nuclear energy but fail so miserably with everything else - fossil fuels, meat, even whaling?
Because they were useful idiots funded by fossil fuel companies. (also US whaling is nearly banned by the US and most countries, and we're not going to go to war with Japan over it)
The elites, powers that be, whatever you want to call them, had their own reasons for killing nuclear power. And nuclear's economics, compared to fossil fuels, didn't make it a slam dunk to adopt despite powerful opposition. So it had no one to defend it.
Environmentalists weren't just useful idiots then (and I hesitate to call people acting in good faith, without any self-interest, "idiots"). They're convenient fall guys today. The fossil fuel industry killed nuclear power and pinned it on the environmental movement. That had the double benefit of keeping their hands clean while discrediting future environmentalists.
