Its ability to supply France in the past is irrelevant to its ability to power global demand in future. The fuel is too limited and the technology too immature to turn this around. Nuclear is uneconomical as it is, fancy future designs even more so, if they ever arrive on scale. Nuclear has a limited future.
The Germany talking point is deliberately misleading. It was in transition and couldn't reasonably have been expected to predict gas would be switched off overnight. But it could reasonably be expected to predict the serious consequences of runaway global warming. The risk of the former was lower than the risk of the latter and while it was unlucky, it was a reasonable bet as a good global citizen that's done more than almost any country in trying to address a problem that affects literally everyone. So you don't get to knock it for doing what most countries weren't brave enough to even try.
No one credible called renewables the holy grail. No serious environmentalist said green energy is already there. They have been arguing for decades for more R&D, expansion of sustainable power infrastructure, local jobs for installers etc. We should have listened. And you might have heard them if lazy, right wing, straw man talking points weren't drowning them out.
I'm sorry but that's just a quick reality check for you.
