As The Hill reported of the vote Friday night, the resolution didn't even come close to gaining the requisite nine "yes" votes which would have forced Russia or China to use their vetoes.
Officially, the final tally was 11 abstentions, two yes and two no votes. After all of Secretary of State Mike Pompeo's lobbying through the summer to essentially make permanent an international arms blockade on the Islamic Republic the US had only two votes in favor: its own and that of the Dominican Republic.
All European members of the P5+1 nuclear deal as expected were abstentions. The vote began via remote means Thursday due to the pandemic with the results tallied and announced by late Friday.
Just before the Friday evening Security Council announcement of the resolution's results, Pompeo voiced frustration, saying the council "failed today" in its mission. He previously said it was "nuts" to allow Iran to purchase and import weapons.
