It would be cheaper implies that taking a hard nuclear option will essentially deprive us of resources to do other things and fix other problems. And we already have CCGT which are a good option for reducing both CO2 and PM emissions. Even if we never build nuclear plants, we can already be very smug about emissions. I don't think using very finite now-resources to solve a then-problem that we're in many ways already mitigating is a good choice. Better to invest now and then use the more developed resources in the future to head it off. I know delaying Climate issues feels bad to us, but for the USSR it is 1962 and the climate becoming an issue is legitimately a long, long way away in a way it is not for us in 2023.I mean, hard commiting to nuclear will power our industries, its just that it would be cheaper to do petrochems. And there are reasons in universe for us to do this, mostly regarding issues in bulk coal transportation among other things. Besides, if Climate Quest comes, it will be incredibly satisfying to say "we have done our part" condescendingly in climate meetings, and will make the transition to renewables much smoother, not to mention all the health effects. Also, I want my Atompunk USSR and by Marx we shall have it!
I could see a more aggressive foreign policy leading to some Linebacker-esque use of the strategic bomber force, or use of the tactical missile force in a similar way.We want an armsrace with the US becuase we don't have to pay for it the people paying for it are the suckers in the army. An armsrace will only strengthen the MNKH and cripple the army as more and more of their budget and personal are going to be dedicated to a nuclear force that is never going to be used. The army has already gathered enough nuclear weapons to end the world 3 times anything more they build is just fucking themselves over.
