It is kind of true.

While of course Bibi did not organize Rabin's assassination himself in any way, he was running a very aggressive hate campaign against him at the time, which many claim has partial fault for the murder.

Some of the demonstrations he led even contained imagery of Rabin as a Nazi, and hanging ropes with a coffin with Rabin's name written on it (Bibi claims he magically did not notice this after the murder, despite photo evidence showing he was less than a meter away).

I cannot even begin to find the words that describe how vile this piece of shit is and how much hate he has caused in Israeli society.
