Part of the agreement with the UN is that the host country for its headquarters allows all heads of state to address the annual gathering.

The Palestinian Authority “stressed that this decision stands in clear contradiction to international law and the UN Headquarters Agreement, particularly since the State of Palestine is an observer member of the United Nations,” the Palestine Mission to the UK posted on X.

I guess the UN should shutter its headquarters in NYC then, seeing as the orange pond scum has decided he rules the world.
