1. The attack occurred not in Israel, not even close to Israel, but deep in Samaria, in a place expected to be part of Palestine. There was no terror in Israel, so Israeli security is still intact, as far as we can tell. 2. The attack was very low-tech. No missiles, not even bombs, nor firearms. As low tech as it can get. There is no reason to conclude that a well-equipped terror organization was involved. In short, this attack indicates nothing bad when Israel and Palestine agree on a border between them.
