WATCH LIVE: Trump addresses UN General Assembly for first time since reelection
Israeli Prime Minister Benjamin Netanyahu, who will take the main stage Friday, has rejected the idea of a future Palestinian state."It will not happen. A Palestinian state will not be established west of the Jordan River," Netanyahu said in a statement in reaction to the push.
President Donald Trump said the move "is a publicity stunt that comes in the middle of delicate diplomatic efforts to end the conflict. Far from promoting peace, the conference will prolong the war, embolden Hamas, and reward its obstruction and undermine real-world efforts to achieve peace."
Efforts to end the Ukraine war as Russia makes repeated incursions into NATO territory
More than three years into Russia's invasion of Ukraine, the ongoing war and efforts to end it will be key points of deliberation.
The high-level general debate comes days after an unprecedented incursion of three Russian fighter jets into Estonian airspace without permission, according to the Estonian Foreign Ministry. Just over a week before, NATO forces shot down Russian drones over Poland.
In response, Trump dismissed the drone incursions, saying it "could have been a mistake."
Ukrainian President Volodymyr Zelenskyy plans to meet with Trump on the sidelines of the UNGA general debate, in what he anticipated to be "a very intense week" of diplomacy. The U.N. Security Council was set to have a meeting focused specifically on the war in Ukraine on Tuesday.

WATCH: Why European countries want to reimpose harsh sanctions on Iran
South Korea introduced a U.N. Security Council resolution aimed at halting "snapback" sanctions after intense negotiations between Iran and European nations broke down and the nations moved to trigger those sanctions. When that resolution failed, Iran said it would "effectively suspend" its cooperation with the U.N.'s nuclear watchdog, the IAEA.
