You're really hanging your hat on the competence of American intelligence in the Middle East for this one?
You’re trying really hard to change reality.
You had a heavily fortified military DMZ between the massive surveillance and military state of Israel and Hamas flying in with kites, bulldozers, and motorcycles. I hope it was merely a massive failure due to arrogance and misallocation of resources, because a plausible alternative is sadly realistic and believable.
And the 9/11 terrorists used planes.
Unless there were literally zero unusual bulldozer and hang-glider citings ever made in Gaza, it shouldn't take that much imagination to see how the three thousandth one gets put to the side.
Yes. Quite easily. We missed 9/11. And nobody can still find Al Houthi.
