Actually, the 1973 Yom Kippur War was masterfully planned, skillfully and courageously executed, took Israel by surprise and came within a hair's breadth of success.
I don't think this is the same thing at all. If the Israelis were unaware of the presence of Silkworms, that's an intelligence failure on their part, but not insuperable. Hezbollah may be tipping their hands.
Shiites/Iran have relatively good track of having success in intelligence warfare. They are somehow more brainy and clandestine than Sunni.
