Note Palestinian’s situation isn’t just due to Israel. Neither Egypt nor Jordan really “want” Palestinians either. Palestinians refugees in Jordan often face as bad or worse discrimination as those in Israel. Egypt could welcome the people of Gaza but don’t either. In contrast after Israel declared itself independent most Arab states in the Mediterranean ejected their historical Jewish inhabitants (roughly equal to the number of Palestinians at the time), and the state of Israel accepted them (it had incentives too to do so). But in short it’s a much more complicated issue than just having a stronger military and Palestinians are victims of more than just one state or political expediency.
