Analysis: Lebanon: Conflict widens to Syria:

"The developing logic of the situation in Lebanon is nevertheless widening the circle of future conflict.

The bottom line is that any future strike at Hezb'allah that does not take into account its status as a client of Iran and Syria, is unlikely to be able to land the kind of decisive blow to the organization which alone would justify such a strike."

Meaning: a Israeli military strike on Hezb'allah would be much more effective, or only be effective, if it includes strikes on Damascus (Isaiah 17) and Iran.
