I think it's been acknowledged by all but Netanyahu that there was an intelligence failure, or failure to act on the intelligence by Netanyahu.

Even had he known about the Plan which we now know his Defence Forces were well aware of in detail a year in advance, it would no doubt have been difficult for him to do much about it. His main goal throughout his Prime Ministership has very obviously been the prevention of the creation of a Palestinian state. He is the one who insisted on letting Hamas have its own way in Gaza deliberately to reduce the authority of the Palestinian Authority. Once the present hostilities are over, whatever the result, he will no doubt be desperate to cling on to power. Hopefully Israeli citizens will call him to account and his days in government will be numbered.
