Any argument that environmentalists run amok is the sole cause of nuclear's failure to launch has to address the fact that these two places, where environmentalists are a lot more likely to get a club to the head than a say at the table, are largely not expanding their nuclear power that much versus, say, solar in China.
In any case, your premise doesn't hold. China is hugely invested in nuke and continues to build as fast as they can. Theyve got 58 reactors operating (about 56 GW) and 33 more (over 35 GW) under construction. Theyve consistently been approving at least 10 new units a year. It's literally in the current 5 year plan.
This is the case in the US, too, as public utilities.

They added 315 GW of solar in 2025 alone, so we agree.
