I think a lot of the criticism of the “intelligence failure” is Monday morning quarterbacking. If anything, the over reliance on electronic intel is the problem. Everyone by now knows the key to surprise is to communicate off the grid.
Not top mention Hamas only had to break through a wall and advance a few miles to cause havoc. A Japanese fleet had to cross the Pacific to surprised Pearl Harbor. If Israel is guilty of anything, it’s complacency.
Focusing on the intelligence failure gets the focus off the atrocities.
