To recap, a vicious, evil regime tried to supply powerful weapons to internationally recognised terrorists, in violation of treaties and UN.

Israel was able to prevent the violation, with no collateral damage and little loss of life, and UN appears to be very happy with it.

So in this subject the Israel haters have no case at all.
No wonder they are frantic to change the subject.

You can claim Israel had some responsibility as the occupying power, but the 1982 massacres were committed by local militia.
Four years later there were more massacres when the Palestinian refugee camps were besieged by the Shi'ite Amal.
There was not an Israeli within 100 miles.

Jim has raised the issue over and over when he is losing an argument, but the facts are against him and over 30 years later there is nothing new to add.
