In all the discussions about what exactly Syria had and the timing of Israel's strike, it should be factored in that Israel took a tremendous risk in this operation. Remember that Syria has some 400 Sarin- and VX-tipped missiles aimed at Israel. Also, Israel occupies a piece of Syria, the Golan, a situation that remains tense and unresolved. In this operation the MAD deterrence seems to have held up, but that is like saying MAD would have held up if the US made a stealth strike against a facility near Moscow. Israel just passed through a Cuban Missile Crisis and no-one seems to understand that. Whatever was out there must have been nasty indeed to induce the wimps Olmert/Livni/Barak to take such a risk, especially after the sting of Lebanon II.
