This is from the Doha Institute survey from 2022 and they had done the same kind of survey also in 2020. The questions asked were:
1) The Palestinian cause concerns all Arabs and not the Palestinian people alone
2) The Palestinian cause concerns the Palestinians solely
and the list of countries that you see below have two numbers separated by hyphen, and the first one is the percentage that said that the Palestinian issue concerns all Arabs and the second is the percentage who said that the Palestinian cause concerns only the Palestinians. I get so angry that there is even one Arab who thinks that the Palestinian problem concerns only the Palestinians. Palestine is under siege and those who are occupying Palestine are supporting by many of the Western powerful countries. So how do the Palestinians get the power to go against such a group of formidable powers if their own Arab brothers and sisters do not stand by them?
