I've been to Sabra and Chatila. I've met with the people and I know the history. The Phalange were full fledged allies of the Israelis. They met and got permission for the move into the camps beforehand. Furthermore, the people in the camp took me to the mass graves and showed me where the Israeli soldiers stood and watched over everything. This was after promising that nothing would happen to the people in the camp. There's so much to this heartbreaking story and it pains me to see people write this off as simply "anti-Israeli propoganda". There's a reason Sharon is known as the Butcher of Beirut in these parts. There's a reason over 200,000 ISRAELIs marched in protest against Sharon when the massacres occured. If you're actually interested in learning more, I recommend "Pity the Nation: The Abduction of Lebanon" by Robert Fisk and "The Gun and the Olive Branch: The Roots of Violence in the Middle East" by David Hirst.
If anyone wants to hear/see more let me know and I'll take some more time.
