So let me understand this.

Israel, which did everything possible to build their nation as part of the international community, was founded with a UN resolution and was attacked and won a defensive war and displaced but did NOT kill a lot of people… that’s illegitimate.

Turkey, which decided that Anatolia should be for Turks despite not being indigenous, genocided millions of Armenians, Greeks, Kurds, Assyrians, and others. They’ve rewritten history to the point where they get offended if you bring any of this up. They continue to genocide the Kurds today… but they’re legitimate.

Saudi Arabia, which was founded on over 200 years of bloody civil war and created their state by overthrowing and expelling literally the monarch that the British made the oft touted pan Arab agreement that supposedly promised the land that is now Israel to the Arabs… they’re legitimate.

Palestine, which has 5 times rejected plans to found their state and has no unified government, hasn’t had an election in decades, and has existed in a state of constant civil war since it declared independence in 1988, they’re legitimate.

Tell me: Precisely what is it about Israel that makes it illegitimate when all the other countries I mentioned plus North Korea, Syria, Yemen, Sudan, Bangladesh, and others where mass aggression and genocide are the norm are considered legitimate in your eyes.

Actually don’t bother. The answer is quite clear already.
