How will Germany pay for Russian oil if they cannot use SWIFT anymore? I know! Our politicians will simply use whatever financial system that Russia will propose. It would be even possible to trade a fleet of AMGs for a week of oil if need be. Removing SWIFT would only delay trade between Russia and Germany not hinder it in anyway. In fact bartering system would produce more efficiencies, a bullet proof AMG G-wagon for instance would fetch more oil than a regular C-class offered to Putin's low ranking officers! All in all, Ukraine gains nothing from this action, it would only give Putin the political ammunition to sell the narrative that Russia is under attack. The US certainly stands to gain everything and risk nothing in this region and its puzzling to me why Ukraine would choose this as a hill to die on as if their self sacrifice would move the hearts and minds of NATO officers on some emotional basis
