Syria wasn't quite ready for the consequences if the Hezzies could have even made 10% good on their promise to hit Tel Aviv.
A prediction based on Nasrullah and Iranian Hitler statements: Hezbollah will launch an attack with 10-30 long range missiles that will disperse incendiaries throughout Tel Aviv or other large city. Each missile will disperse the incendiaries in the form of 10-30 individual bomblets in a Mirv effect. The idea is to create a firestorm and overwhelm fire-fighting efforts.
