They just didn't realize how real this particular plan was. It's quite likely Hamas is regularly bluffing similar attacks in many potentially-compromised channels. If they then see Israel react, they've received info about Israel's capabilities & tactics – and maybe even ways to misdirect Israeli forces with future feints. And any real plans may stay hidden amongst dozens/hundreds of other "false alarms".
Yes, but I believe the post to which I was replying used "the initial attack" that Israel "failed to see coming" to refer to Hamas' October 7th attack.
Hence my reference to Hamas' likely chaffing of Israel's intel, and Israel's false-alarm fatigue, before that "surprise" attack.
Of course Hezbollah likely uses similar tactics - but if as deeply pierced as this latest attack implies, they'd have to wonder if any comm successes they thought they had were just Israel leading them on. I doubt Hezbollah has surprised Israel recently!
