my guess is that russia and china are telling them to wait for the brics summit a few weeks from now. if a huge war broke out now it might empty the summit by making it seems like countries are taking sides. the summit is set to be attended by 150+ countries and launch an alternative to swift which would free iran of sanctions helping their future war effort at the same time that undermines the us's economy and it's ability to support israel. said alternative to swift would also make the us blind to who is doing trade with iran avoiding secondary sanctions.
