Fairy tales. Actually all big massacres of Palestinians were made by ur Assad psychopath regime:
1976 Tal al Zaatar
1983 Tripoli
1985-1987 War on Camps massacres.
Even Sabra and Shatila in 1982 was done by Assad's ally Elie Hobeika.
When after the massacre Hobeika and Jaja fought each other Israel supported Jaja while Assad supported the butcher of Sabra Hobeika. Fact.
Now Assad massacres and starves Palestinians in Yarmouk camp. Nazi style.
ISIS is nothing but Iraqi Baath. Same as Assad is Syrian Baath. Both same exactly shyt.
Israel signed pullout agreement with Lebanon in 1983. Hezbollah (it was called Islamic Jihad and Islamic Amal then) and other Khomeini-Assad goons foiled that agreement as result Israel STAYED in Lebanon for another 17 years.
Qadrillions. LOL where from u take these numbers. As I said since the beginning of first Intifada ~30 years ago about 10 K were killed total.
