If Nasrallah has evidence linking Israel to the Hariri case, let him present it to the UN investigators. Nasrallah's claims that Israel tried some 10 years before Hariri's assassination to drive a wedge between him and Hizballah indicates nothing about the assassination. It is difficult to see what motive Israel would have to remove Hariri, a strong man who could stand up to the Shiites. For this very same reason, Hizballah had a motive to eliminate Hariri.
