Syria ready to finish off Hezbollah?

Rumors about Syria wanting to get rid of Hezbollah have been spreading increasingly since the killing of Hezbollah strategic mastermind Mughnieh in Damascus. Now, good ol' shaky Abssi (back from the dead) has vowed revenge against those who started the sectarian war that has lead to the takeover of West-Beirut, saying that suicide bombers would not spare God's enemies wherever they are.

Assuming Syria's sponsoring Fatah al-Islam, it seems natural to conclude that Assad has had it with Hezbollah. They must be wanting that peace with Israel pretty badly.

Addendum: a friend wanted to add another argument in favor of the idea that Syria is trying to ditch Hezbollah, namely the "new documents" that president Suleiman apparently has received that would provide additional support for the claim that the Shebaa Farms belong to Lebanon. A plausible theory would be that these documents came from Assad. Is this Syria's way to make Hezbollah even more irrelevant?

Addendum II: someone pointed out another event that supports the theory that Syria has had enough of Hezbollah, namely the cancelling of the national strike by the Labor Union on May 7. Interesting enough, I had written about this angle, but subsequently forgotten about it.
