Even with this in mind, I'm sure a significant Turkish population will still support Palestine or the idea of another Jewish expulsion. For one even discounting racial consideration, modern Turkiye is overwhelmingly muslim. And the idea that the third holiest site in Islam is under occupation will naturally attract these people to the Palestinian cause. So in the long run, as I said it before the advantage goes with the Palestinian because not only they could garner the sympathy of the Arabs, they could garner even non-Arab sympathy by the basis of religion alone. Not only the Turks but as far as Indonesia and Malaysia.Just a quick reminder about what our Palestinian "brothers" did against the Turks 100 years ago... They have been reaping the fruits of their deeds for a century now. Just stay neutral and leave Israelis and Palestinians sort their problems out. No need to take sides.
Of course, I'm saying this knowing full well that there are many secular Turks who don't want anything to do with religion or even outright defending Israel, but there's always that added bonus.
And fact on the ground remains, Israel is a lake surrounded by Arabs and Muslims, many if not most dislike them and only the consideration of the U.S stops them from doing anything. Take the U.S out....things will be interesting.
