Netanyahu spoke to a largely empty UN General Assembly hall after most delegations walked out, a sign of how isolated Israel has become diplomatically.

• Diplomats left the chamber in large numbers as Netanyahu took the stage, clapping on their way out.
• The walkout was widely read as a coordinated snub rather than scattered protest.
• Israeli officials were seen photographing or recording who left, suggesting the exits are being logged.
• Governments keep private lists of who backs them and who does not, and this kind of public move gets remembered.

Outlook: Expect quiet diplomatic payback against countries that walked out, and more pressure on Israel at the UN.
