No, that is not quite right.Egypt and Jordan didn't allow the humanitarian corridors because Biden had no plans to allow the Palestinians to go back to Gaza after. There are already US soldiers there and have been for the last year. I can't help it if you aren't paying attention.
Egypt and Jordan didn't allow the humanitarian corridors because Netanyahu had no plans to allow the Palestinians to go back to Gaza after. Biden didn't really care either way. He would have taken any agreement just to get out of this mess without having to do something. He also complained more about the Israelis than about the Palestinians when such an agreement didn't manifest. But still couldn't bother to do anything.
