I don't buy it. The only way this could be more humiliating for the US is if Trump agreed to do a public apology from Tehran. No way the Gulf countries and Israel would even entertain the thought.
I wonder how badly damaged the Gulf countries as Israel were in the past few days.
I have the impression a lot of the damage caused by Iran is being hidden and downplayed.
The Gulfs would just follow whatever US wished. They also received the grim reminder that US being far away can just go at a moment notice. Iran is there for eternity figuratively speaking. They all need to learn to live together
