First fingers will point to Israel, of course. But I would suggest that Hezbollah start to look over its shoulders to see if there are any even more radical Shiite groups wanting to act. To them, the Sunni extreme Hamas would be a legitimate target, especially on this Shiite holiday. Glances should also be made at al-Qaida and company. They may want to punish Hamas for allying themselves with Shiite Blasphemers. With all this insanity, Israel is likley not involved.
