How exactly do you see Russia as an existential threat to the EU? Putin does not seem interested in conquering the EU, at all. He’s never mentioned anything of the sort that I know of, and he’s not the guy to mince words about his intentions. He’s not even really interested in conquering all of Ukraine, because he did not at any time mobilize the kind of force that would be needed for such an endeavor.

I mean, yes, Russia’s nukes are an existential threat, but to the whole planet, not just the EU.
