And back in 2007 - recall the recent Nashville bomb - was that a test to disable defense systems?

"Surveillance is providing clues about how Israeli aircraft managed to slip past Syrian air defenses to bomb the site at Dayr az-Zawr. The main attack was preceded by an engagement with a single Syrian radar site at Tall al-Abuad near the Turkish border. It was assaulted with what appears to be a combination of electronic attack and precision bombs to enable the Israeli force to enter and exit Syrian airspace. Almost immediately, the entire Syrian radar system went off the air for a period of time that included the raid, say U.S. intelligence analysts...it seems that Israel was able to do this cyber attack from the air." https://www.military.com/defensetech/2007/11/26/israels-cyber-shot-at-syria
