What are you referring to? It's nowhere even close to the same scale.
Although if you consider the assassination of Rabin, which was carried out by an Israeli settler extremist, then yes, that was something that caused a terrible impact. It's possible that if that had not happened, Rabin would have managed to get us to an actual peace agreement. (Still his murder didn't stop the peace process - it continued. What really stopped it was the refusal of Arafat to agree to a deal, and the second intifiada.)
