The power differential in the Israeli - Palestinian issue is lopsidedly in favor of the Israelis, so ultimately they have all the power (this is doubly so when you consider they are fully backed by the US). Therefore any attempt to engage them militarily by way of Hamas or any of the other usual suspects, will obviously securitize them into thinking they have to leverage their power to suppress what they regard as threats. Therefore, having a paramilitary organization dedicated to their destruction (even worse an Iranian proxy) only incentivizes the Israelis to be restrictive and seek military solutions. Once you remove Hamas and other similar groups, the Israeli excuse to securitize and restrict goes away. That would've been the preferred approach, but now that Hamas have effectively done what they were created to do, they are probably going to be destroyed and untold amounts of Palestinians affected (killed, injured, displaced, or lacking in basic services to survive).
