It is more than obvious that both Hezbollah and Israel have been knee-deep into the Syrian morass.
The official proclamations coming from Netanyahu et al have been pretty predicable. They're preventing advanced weaponry from falling into the hands of Hezbollah.
Of course they are.
But is it possible that both Israel and Hezbollah are in Syria propping up the same guy?
Both have plausible reasons for preserving the Assad regime. In fact, they both have much to lose if Syria devolves into a failed state on the lines of Iraq.
The Likud brain trust doesn't mind failed states per se; they've certainly done their best to ensure that Lebanon goes down that road. But it's important to them that the anarchy be manageable.
And Syria is out of control.
