Israeli Prime Minister Benjamin Netanyahu’s speech before the United Nations General Assembly could almost have been mistaken for business as usual. He stood at the dais Friday displaying a prop much as he often has: This time, he brought placards that itemized the perfidy of his nation’s enemies and illustrated the scale of Israel’s victories over an array of militant groups in the Middle East. On his lapel, he sported a large QR code, by which anyone watching could access Israel’s account of the horrors unleashed during Hamas’s Oct. 7, 2023, attack and the brutal war that followed in the Gaza Strip.
