Like I said, Israel wishes to get a full-on war going so they can decimate the population of Lebanon.  As far as I can see, the 'official government' of Lebanon is some gaggle of lackeys of the West.  IIRC, the last 'president of Lebanon' had his office (and his ass) in Saudi Arabia much of the time.  It's a Juan Guido type situation.  Even so, they probably don't want to see 80% of the population ethnically cleansed to make way for the Greater Israel project so they'll do anything to avoid going to war.  Most certainly including lying about an Israeli attack using novel weapons of mass destruction.

Hezbollah seems like the real government of Lebanon and who the people trust.  With good reason.  They more than the puppet government wish not to see their people final solution-ed and have stayed relatively mum about things as best I can tell.  Nasrullah, however, has said that 'he knows more about what is where at the port of Haifa than at the port of Beirut.'  And he has a reputation for making good on his promises.  We'll see what happens next.  I would expect fireworks in Jerusalem as trade for the Beirut flash-bang.  Seems more of a fair trade.
