Hamas is correct. "Israel" is a European settler colony, and like other European settler colonies, it depends on the removal of the indigenous population and theft of their land. Palestinians have exhausted every possible alternative to violence over decades, and it's brought them to the brink of extinction. Their options are to fight for their lives and right to return to their homes, or to be exterminated as a people by the Israeli state. Palestinian Jews existed before Europe created Israel, and they'll exist as equals after Palestine is free.
