I don’t think it is fake.
Do you remember when the Norks captured the Pueblo and the captain signalled during his television interview that he sounded cooperative under duress and didn’t really mean it?
I see the same signal in Israel tweeting exactly the same words as the US. In my opinion they are saying that this wasn’t their choice and they had to deny it for the sake of preserving what is left of the alliance.
Don’t they have call blocking in Israel?
