Poland? Finland? These are some of the countries that have been pushing the *hardest* against Russia, why would anyone think they’re going to peel off? Poland in particular, they’re the only country in Europe where a plurality actually wants to deploy troops to Ukraine.
And again, the logic makes no sense, they’re hurting their own consumers way more than they’re hurting their targets. Even if you ignore the fact that the impact of their sanctions on the export side are spread out over countries with over a dozen times their GDP, while they have to eat the full impact on the import side.
