Israel did something similar when it took out the Bushear plant back in the 00’s. Syria went dark, the Israeli’s took out the plant, and they came home and had lunch.
My guess is the systems were a) not on line, b) not ready for prime time - potemkin village style, or c) disabled through something clever.
Huh? The Bushear plant is in Iran, not Syria.
Israel used their Air Force to take out the Iraqi Osiraq reactor in 1981.
They did bomb the still under construction (but not yet operational) Syrian nuclear reactor at Al Kibar. And that was being built with the help of Iran and North Korea. THAT successful Israeli attack occurred in 2009, so you are partially correct.
