The problem with your statements is if the Jews are doing what you said, they are doing a poor job of it. Jews and Muslims represent about the same population across all of Israel including the Palestinian territories.

The number of Palestinians have tripled since 1948.

So, help me with the math... how does this constitute "ethnic cleansing"?

Historically, the blockade has been by both Israel and Egypt only applies to military materials and weapons (and clearly it is not very effective given how many rockets Hamas had (except in times of active conflict). Gaza has an airport and port, that could be developed, but who wants to invest in war torn nation. Expensive infrastructure investments will not happen until everyone is certain, that future attacks like October 7th are history.

Egypt also prevent immigration into Egypt by Palestinians. In general, Arab countries are not interested in Palestinian refugees for a host of reasons ranging from economic to security challenges.

Again, until the Palestinians change, no one wants them. My guess is that if peace comes and the emphasis shifts towards economic development, not only will Palestinian standards of living improve, but their skills will be sought after by other Arab nations.
