The Kuala Lumpur findings have been widely accepted and reported
Really?

I have no "case" about Sabra-Shatilla except that Israel's version stands up to scrutiny and should not be dismissed.
Reputable "eye witnesses" tell lies about Israel.
Remember those good nurses on the Mamara who "saw" Israelis throwing bodies into the sea, yet every single person on the ship was subsequently accounted for.
There were no bodies.
I doubt the nurses made the story up.
The activists gave it them.
That is what they do, and the gullible saps like you lap it all up.
