Yes, they had intel about the attack method, but not the dates, or even if it was real or aspirational.
This goes to my question about the person break into your home... What changes or adjustments could Israel have taken based on the intel? Like I said, maybe they could just place a bunch of battalions along the entire border, but then maybe Hamas would just lay low until they were gone.
