Not really. Imagine a world where Ukraine, Germany, Poland, Sweden, Finland, Hungary, Romania and Bulgaria scaled up nuclear power in the 70s. In that situation Putin wouldn't have had any money for his army in the first place.

You have to think about the system as a whole as I said, not get blinded by some detail right now.

And yea, scaling up nuclear right now is probably not super useful as batteries and solar have dropped so much in price. But we certainly shouldn't shut down nuclear reactors like Germany did.
