That is the dumbest thing I've ever heard. As long as Hamas and Palestinian Dissidents keep engaging hostilities against Israel, Israel will continue to have free licence to respond. Those home made rockets are a far cry weaker than then the weaponry Israel returns fire with. The pen is mightier than the sword. If the Hamas disbanded, and the Palestinian government accepted a partition agreement, the Palestinians would actually have legitimate international support to rebuff Zionist aggression.
It's one thing if the Palestine was waging a legitimate war of conventional means. But what you're advocating for is genocide of the Israeli population.
