Israel when it carries out the very actions you so loudly condemn when carried out by Hezbollah or Hamas
Not true Steve.
Israel does not target civilians or attack indiscriminately as both Hamas and Hezbollah do.

Israel had responsibility because the Israeli army was present at the camps, illuminated the camps so that the killers could see what they were doing and then stood by while the horror was perpetrated.

You need light to identify enemy positions.
You do not need light to carry out indiscriminate murder in a crowded camp.
The Israelis stepped in and stopped the massacre.

And there are plenty of witness accounts that the killers were virtually goaded by Israelis to do what they did.
No, there are not.
