This shit might dangerously soon be enough for Putin to just say "yolo". Also, insane how the entire world is quickly responding to Russia, while noone gave a shit about the US killing literally millions of people. Or the Saudis killing more innocent people right this moment than Russia is. And they will be allowed to continue to do so. It looks like the US hegemony is getting only stronger, not weaker, no matter what it does.
For... utilising a bank telecommunication system? Extremely unlikely. Especially since it could be done in parallel. Set up CIPS, continue allowing SWIFT communications. Something happens to SWIFT, congrats, it's meaningless, just use the other one. The national equivalent of your wifi going down while you're watching a video on your phone so you just switch to 5G.
