Why patch out a bug that’s working in our favor?

Commit to renewables. I’d advocate for a nuclear powered off-ramp from fossils whilst renewable capacity and infrastructure is built, but I get that each nation has its own history with fission.

Energy security is fundamental for a robust society and economy - otherwise you’re subject to pipeline shutoffs/attacks, oil embargoes/quotas, or another angle for outside nations to influence or control you. For example, if you’re chill with the French and build your economic strategy around buying their surplus energy, that strategy predicated on the French having a surplus to sell you.

If you’re a (western) European leader returning to Russian energy is at best shortsighted amnesia, at worst blatant malfeasance. There’s several reasons to not go back to Russia:

• Official legal based sanctions on Russian energy
• Ukrainian drone based ‘sanctions’ on Russian energy
• Russia’s track record of energy blackmail/hybrid warfare
• LNG and oil production available in your EEZ/the EU, albeit at higher cost than imported
• Domestic solar, hydro, and wind manufacturing/generation is ramping up
• French nuclear energy exports
• Domestic politics ie. voters turning against Russian imperial aggression/expansionism

Eastern Europe has a slightly different incentive mix, but there’s still a lot of reasons to not

Devils advocate, but given the way they’ve been building metal sheds around the prior tanks and almost completely negating the main gun, a missing turret might just be a weatherproofing issue for the Orks Russians.

It’s not like a main gun helps you survive a mobility kill from the umpteenth TM-62 in the dirt that got replanted after the last assault failed.
