This is a bad take. Egypt, and others, refuse to take "Palestinian refugees" because doing so would make them complicit in Israel's ethic cleansing. Why should Palestinians be forced off their own land?
> Russia doesn't allow ukrainians back to the occupied territories
I don't know that to be true. AFAIK, Russia would like the population there too.
The problem seems to be that Palestinians don't want peace, or are unable to separate themselves from the terrorists government.
Its also not true that Egyptians hate Palestines. In fact I would say its rather unison that they feel great sympathy with the Palestines in the occupied areas, and the boycott of companies that support Israel is strong. McDonald's and Burger Kings are mostly empty and there are Palestine flags at shops, stickers attached to products you buy and people are sad about the situation.
Gaza is a mafia state under control by Hamas, who likely control all aid coming into the country and certainly the Iranian military funding.
Israel seems to apply a 10x minimum response to any Israeli casualties over the years. This attack is well above the 10x number already.
And remember, the Israelis do not completely surround Gaza. Egypt is complicit in closing the walls of the prison on Gaza, and Egypt I'm told hates the Palestinians more than Israel does. I wonder why this is, Egypt did manage/oversee Gaza for 25 years and I guess said "no thanks".
AFAIK, it's not like the Sinai peninsula is some valuable land, I think Egypt has room to take in Palestinian refugees. They simply refuse to do it. I have not gotten any good reason why they hate them. I guess the Lebanese hate their Palestinian enclave. It is clear the Arab world doesn't care about the Palestinians, and a common brotherhood of Islam doesn't carry weight.
