In much the same way that the UK/US and Israel are using ISIS to smash up Syria, the Israelis used Christian Phalangist terrorists to massacre thousands of Palestinians they had expelled from their homeland, and who were forced to take safety in Lebanese refugee camps.
The IDF lit up the sky with flares so the massacre could take place through the day and the night. It was as bright as a sports stadium at a night time football match said a Dutch Nurse.
Interestingly there are IDF war criminals now based in the United States, with senior roles in well known corporations, who openly brag about their role in this holocaust on Linkedin.
I will add their names to the roll call of genociding war criminals to this post as I see fit.
