Lol not a chance. Maybe there’s been some work in the public sector, but remove Amazon and MS and you’ll remove the vast majority of companies.

The EU should push for their own cloud and “encourage” (ie “there’s a chance that in 5 years you won’t be able to use anything that’s not in the EU, better prepare”) companies and the public administration to migrate.

That’s why they want Greenland.

Most of these are not really a problem though, even less for the kind of psychos that run the EU. Sanctions can be lifted, and Ukraine shouldn’t be able to do much against both Russia and the EU. While renewables and nuclear are increasing, Russian energy could help until they are 100% ready. Voters won’t do much if they are told “see, the US is trying to scam us, and in these trying times we’ve struck a deal with Russia and you’ll be paying less for power and heat”.

The problem with striking a deal with Russia is that it’s not the most reliable partner right now (your 3rd point), but the people in charge can ignore the rest and have no problems sleeping.

Edit: this is not a defense of Russia but a critique of the powers that be in the EU.
