Its possible there was some element within Israeli intelligence that wanted to exploit an opportunity, god knows there's no shortage of genocidal elements in the military, but everything about this runs counter to everything Israel has been trying to do for decades. Nobody gives a fuck about the Palestinians, the peace process is long dead, they had normalised relations with most arab states, Iran was effectively contained, and there was virtually no significant global resistance to their strategy. There is no way in hell that Netanyahu would willingly place all of that in the hands of the fates, certainly not at the probable cost of his own political survival. If you hold all the cards in a poker game, are you really going to upend the table in the hope of snatching the pot in the chaos?
