It's funny that in Europe those posirions, generally summed up as appeasement towards Putin, are mostly spread by the extreme right (Le Pen in France currently being a prime example).

And appeasement is what those proposals, territorial concessions etc, are. And as appeassement in the thirties the effected countries are not asked their opinion (the future allies gave away parts of Chekoslovakia in Munich without asking).

Appart from that, the general observation holds true: The US definition of socilicsm is only applicable to the US, in every other country it is just laughable.

EDIT: Regarding embargoes of oil and gas. Those are the last things the West can take away from Putin. There is nothing left after that, Putin will entirely depend on China for revenue, making a defacto puppet of Bejing. Not sure anybody wants Putin in a position where he has nothing to loose. Sure, put those embargoes in place as an answer to something Putin did. And not pro-actively, becaise that would be escalation. As a coubter example, the Greens in Germany, by no means at risk as being seen war hawks, a strongly in favor of sending heavy arms like tanks to Ukraine.
