Israel isn't a large country. The lack of active patrolling along the gaza border was grossly incompetent, unacceptable and entirely on the leader of Israel. Simple patrolling would fix any intelligence failures. They had zero. The response time to enemy forces was a failure, and basic security aspects and the settlement outposts failed.
This a entire failure from top to bottom. There was no reason why these communes couldn't have been more prepared.
Bibi will have to answer that after the war in Gaza ends.
