At this point, anything that happens in the Middle East could be cited as a precursor to WW3. Can't say I wouldn't have done what Israel did though. I'm really surprised that Syria did absolutely nothing about it. They're admitting that foreign countries can attack them without expecting retaliation. Even if it wasn't a military retaliation, because they know any aircraft or tank sent into Israel would be vaporized, they could have made a big scene to the press and lied like usual. They handled it pretty badly.
