And that is relevant how? The UN has long ago failed in its purpose, let them bleat about "international law" all they wish. The fact is, The Arabs lost both East Jerusalem AND the West Bank fair and square in a war that the Arabs started (the Six Day War, in which, yes, Israel attacked first, but then, what would you do if hostile armies were surrounding your borders with every clear intention of attacking you). This was confirmed by their loss in a war that they DEFINITELY started, namely, the Yom Kippur War. You don't get land back when you start wars and lose them.
Your reliance on laws that don't apply to circumstances won't get you very far in the modern age. I strongly recommend instead that you grow up, put on your big boy pants, act your age, and look at the world as it really is, rather than as you think it should be in your whiny, anti-Semitic (or if you prefer, I'll use the term "Judeo-phobic") little pea-brain.
