Why would they do that? To make themselves more of a pariah State? To lose allies, be further sanctioned, be prosecuted for war crimes, to tank their own economy, put their own citizens and Jewish people at more risk from antisemitism/Israel hate?
Jewish people in general are pretty intelligent and successful. They know Palestinians have access to cameras, internet, social media and media outlets and will tell everyone what they’re allegedly doing with evidence if they have it.
They could be more successful in carrying out a genocide by killing more Palestinians in one go instead of dragging it out for two years and shooting them here and there and also risking soldiers being on the ground. Would have saved $ billions as well in the cost of the war as well as thousands of soldiers lives just from not bothering to evacuate civilians when they bombed the hell out of Gaza.
They are already accused of genocide, they have nothing to lose.
Logic then dictates that is not Israel’s intention surely?
