Lots of things to address in your links. The fact that that is no longer the Hamas charter, the current charter recognizes the israeli state territory.
From the link on Israel disengagement
The United Nations, international human rights organizations and many legal scholars regard the Gaza Strip to still be under military occupation by Israel.[5] This is disputed by Israel and other legal scholars.[6] Following the withdrawal, Israel continues to maintain direct control over Gaza's air and maritime space, six of Gaza's seven land crossings, maintains a no-go buffer zone within the territory, controls the Palestinian population registry, and Gaza remains dependent on Israel for its water, electricity, telecommunications, and other utilities.
They never actually disengaged, and have killed a lot of palestinians through this humanitarian nightmare theyve enforced.
And that is quite some revision to the 1948 arab israeli war. It was palestinian territory and israel were the invaders, that was the beginning of the killing and exiling of palestinians from their own land. From the modern day fraction of territory palestinians now have, and the massive death toll of palestinians, you can see how that has proceeded over time. Any resistance to this extermination just gets used as justification to continue it.
