Because annexing and driving people from their homes well starving them to death is doing so much for them. Remember when Israel shot those hostages who were trying to get back to Israeli lines waving a white flag? How many times has similar incidents played out for the Palestinians but is unreported? Hard to tell when your purposely preventing journalists from entering and reporting and shooting those who do.
Hamas is not getting a free pass, the same people who are declaring this a genocide also declared Oct 7th a genocide as well. Right now Israel is the aggressor, going well beyond self defense.
The lesson I have seen from Israel at the moment is work with us and we shall only slowly drive you from your home/kill you and force your family out (West Bank). Work against us and we shall do it quicker (Gaza). No where in there is Israel providing a option to peacefully co-exist.
Israel gave up Gaza in 2005 in the hopes it would bring peace. It did not. Nor did Hamas ever make peace with the Egyptian government, further isolating it's people.
The WB is another story, it was never Palestinian land, it was either Ottoman, British Mandate, Jordanian or Israel. It is strategically necessary for Israel to hold it, otherwise Israel is only 14 km wide and completely vulnerable to attack. Both populations are expanding, but thee is not enough land or water for both. Even if you gave the entire WB to the Palestinians they would not be content, they are very clear that ALL OF ISRAEL must disappear and the Jews dead or gone. On the other hand most Israelis are willing to have Palestinian settlements within the WB, despite the security risk and the immense cost in blood and treasure to ensure they do not conduct another Oct 7th.
Had the Arabs won in 1948, the Jewish population in the ME would have been a sad footnote and no longer exist. The Jews have been ethnically cleansed from every other Muslim country in the ME, despite being there for thousands of years. Under the Israeli "Ethnic cleansing" of the Palestinians, the population has gone from 156,000 to:
West Bank (including East Jerusalem): 3.19 million
Gaza Strip: 2.17 million
Territories occupied in 1948 (Israel): 1.7 million
Clearly the Israeli don't understand ethnic cleansing and need to take lessons from the Arabs:
The Jewish population in Arab countries declined from around 700,000–900,000 in 1948 to a mere 12,700 in 2019,
