Reply #4: "Now" isn't quite the right word.

A week or two ago Nasrallah was saying without a prisoner exchange there could be no ceasefire, no matter how many Lebanese were killed. But he also said that Israel fell for his clever ruse, drawing them across the border so Hezbollah could kill as many as possible before driving them back.

Nasrallah has three unalterable requirements:
--no Israelis on Muslim ground
--prisoner exchange, with Kuntar the kiddie-killer as the star innocent in his celestial pantheon
--no disarmament

All else is blather.

BTW, these are the victory conditions for Hezbollah, so all he's saying is "Let the slaughter continue until we win."
