1) If you are fleeing or have to drive anywhere, use your World Cup flags and strap them to the roof of your car. That's what the busses evacuating the Europeans are doing. Let's see if the Israeli bombers target more Germany or Brazil fans. My guess would be the former (for obvious reasons), but the international outcry would be greater (lighter skin).
2) If you're home has been laid to rubble by the Israeli bombers and you were lucky enough to escape, the palaces of Jumblatt and Hariri in Ras Beirut remain empty and are available for squatting. As veritable 100% Lebanese leaders, I'm sure they won't mind extending their hospitality to persons from different sects.
3) To Hezbollah: Change your name and/ or logo. It worked for Philip Morris.
