People like Merkel didn't exactly think about long-term prosperity, given their climate policies. Energy shocks would've been, I assume, much stronger if they only started to happen in the 30s. The economic consequences (energy inflation, supply chain crisis) were not considered, although people have warned. Some acted (I think fennoscandic countries implemented effective heating regimes in the early 10s already for example), but many didn't learn from the 1970s energy shock caused by energy dependency on incompatible political systems and Russia's disorganisation of representation in the 2000s. Sanctions/disentanglement would've been necessary in the 2000s when Russia became centered around Putin.
SOL is high enough to defend against fascism. Don't fall for the propaganda of imperialists.
This war is so bad already, but it could be much worse (even with MAD).
