The checkpoints and control of roads in the West Bank prevent Palestinians from moving freely. The PLO "controls," The West Bank, but when an occupying nation controls many of the roads, preventing usage of certain roads by the citizens of your territory and only letting their own citizens travel on them, how can they be considered independent? They lack basic sovereignty, with their citizens not being able to move within their own country due to an occupying force. You claim there is no authority to undermine, but even if correct, the reason for a lack of authority is squarely on Israel.

The idea that Palestine's population has grown for the entire conflict falls apart when you look at the late 1940s, where over 700,000 Palestinian Arabs were expelled from their homes by Zionist militias. It was almost half of the Arab population. In just a few years, zealous Zionists used violence to flip the demographics of the region to favor Jews over non Jews. This wasn't genocide, but was undeniably ethnic cleansing. It's an important piece of context that Israeli fascists have tried to keep out of the conversation, focusing on population trends after their ethnic cleansing and assuming people won't investigate.

I might describe Isreal's practical intentions as genocidal because that's the only way their strategy can make Israeli citizens safe like they claim to be working towards. Bombing Gaza does not make Israel safer unless they decimate the population enough to exert authoritarian control over the survivors. If they wanted Palestinians to live alongside Israel peacefully, they would ensure that there is a strong Palestinian state with little motivation to invade. If they got rid of settlements in the West Bank, funded a Palestinians state and reinvigorated their economy, and mutually agreed to harshly police hate crimes in both states, then they could coexist. The only ways to defeat Hamas in Gaza through force would be occupation of Gaza, or the expulsion of Palestinians from Gaza.

The reason they don't go all out on purging Gaza probably has to do with Arabs outside Palestine who might attack if it happens too quickly. Israel has nukes, but they still want to avoid all out war. The long term goal of this subset of Zionists, genocidal Zionists, is to take over all of Palestine eventually, something that would likely be genocidal. Some Zionists want two states, but the Zionists in charge want a single Jewish theocracy.

I want peace and safety for Jewish people and Palestinians, something that will not happen without a true two state solution, or a single secular state. The long term plan of the state of Israel is ethnic cleansing at best, and genocide at worst.

The situation with Egypt requires contextual knowledge of their history with the Muslim Brotherhood. Hamas is a breakaway from the MB, and still ally with them. Egypt's more secular military overthrew the Muslim Brotherhood's democratic government, and the current government doesn't want them to rise again. Letting in Palestinians would let in Hamas members, who might create problems for the government. It's not the peacefulness of Palestinians, but the politics of Egypt that prevent them from accepting refugees. If Hamas was exactly the same but would oppose MB forces in Egypt, Egypt would probably let in some refugees. However, it's hard for a nation with Egypt's problems, to deal with so many refugees by themselves anyways. Israel, the ones creating refugees out of Palestinians, can't expect their neighbors to happily foot the bill of caring for people who's property they stole and destroyed.
