Some of those “visitors” have been violent and tended to hijack plans and blow themselves up. I expect to get the 3rd degree if I’m ever in Ben Gurion.
That said, all of the nonsense should have stopped the moment a US passport was seen. Basically the customs agent should have “kissed it” and “worshiped it”. Once he’s one of us he’s one of us and none of the rest of us should take these slights lightly.
