Besides, it's not "the West" who wants to cut Russia out, it's only the US. European politicians don't seem to be that supportive of this idea and they are the ones who have legal power here, not the US.
Tbh, it seems to me that Russia would actually profit in the long-term from yet another US illegal abuse of SWIFT. They already provide their own ISO 15022/200022 compatible solution, cheaper and decentralized https://www.cyberft.com/
Creating further inconvenience for business would simply drive them to consider additional diversification and redundancy, given that there are alternatives.
The US is really overplaying its hand under Biden, it's quite sad to watch such a complete mishandling of foreign policy and energy policy. This is almost certainly the US presidency that markets the tangible decline of US global order.
I'm not sure if Trump understood this explicitly, but he did implicitly: the correct way to "defend" from Russia and China is not to try to freeze them out, but to make them active participants. If the loss of SWIFT hurts Russia, Russia would have a vested interested in its protection. Instead Biden is desperately trying to force Russia to accelerate SPFS, and in these circumstances they're going to send all of Europe along with Russia.
The self-caused European Energy crisis means that the EU has to play with Russia at this stage in the game. If Biden pushes the removal of Russia from SWIFT, Russia just has to tell the EU "we only accept payment for LNG via SPFS, in Rubles, Euros, or physical delivery of gold". And that's it, Europe immediately is adopting SPFS because the alternative is freezing to death.
The US is not going to ship enough LNG to the EU to keep it going - it's not even going to be able to keep Nord 2 offline. It's such an absolute negligence of foreign policy that I'd almost think the US is intentionally playing into Putin's hand.
He lost the 2020 nomination because he was absolutely terrible. You are ignoring the abysmal results before the first southern state even voted (south carolina). Him being gay didn't even register given how badly he killed his chances of him just being himself.
Really not need, they will just build their own. Believe Japan is already allowing them to use their banking clearing system. I'm sure they and China already have one. All this cyber attack stuff are really not worth while when country can just build their own SWIFT type of system.
