Ahhh. This is brilliant. This doesn't really have anything to do with Iran. This maneuver is for the UN. I believe this is for two things.
1) To test the UN following Haley's last appearance and pseudo threats. Are you now with us or still against us?
2) To further advertise the UN's complete and utter impotence and disdain for their largest donor and most powerful member.
I think they expect the UN ignore us and put another notch in the belt for when the USA cuts funding. If the UN were smart, they would assemble. But I don't think they are smart.
Maybe the UN can move to Jerusalem?
Is there any doubt as to what the answer to that is?
