Pickman's model

but we're not talking about the military. shin bet is not military intelligence. and presumably there are hundreds if not thousands of israeli intelligence collectors and analysts in a range of services tasked with monitoring hamas and the wider gaza strip, not to mention mossad looking at iran and lebanon among other places. for my money this was all collected but for a range of reasons - hamas operational security, a hamas deception operation involving a suggestion that this was something to do with the west bank rather than an invasion of israel, a failure to join the dots on collected information or whatever - nothing was done about it. the mail today says the zionists won't comment on the hamas videos until the war is over. but by that time i rather think larger events could crush that out of that news. but it's not just israeli intelligence. surely if mi6 or gchq or the nsa or cia had got wind of it through human sources or signal intelligence they'd have passed it on. as indeed the egyptians appear to have done.Re: Intelligence failure I think it can be reasonably argued that Israeli society up until this point had become seriously divided over the constitutional reforms that Netenyahu and his far-right friends wished to push though. So much so that Netenhahu was heard to accuse members of the military as being compromised by the left. Netenhayu's personal motive for the reform is to protect himself from corruption charges. in any event this may well have led a combination of the leadership being unwilling to listen to the military and the military themselves taking their eye off the ball.
