Your question: why would Israel embark on a complex and enormously risky attempt to kill Hariri - who at the time was the most moderate candidate for Lebanon's presidency and the darling of both the U.S. and France - solely in the hope of being able to somehow incriminate Hezbollah at some future date? Possible Response: 1- The fact that Rafiq Hariri was close with countries like US and France is precisely a threat to Israel. This gives Lebanon power of presence in the world and if Hariri could protect Hezbollah's arms, this would be a problem for Israel giving his closeness with also other countries like Saudi Arabia and the royal family whom money hands US official like to go kiss. 2- This is without mentionning that Israel precisely wanted Syria out of Lebanon because of it refusing to stop arming Hezbollah. This could be the first aim of the murder. The inculpation of Hezbollah is plan B. I personally didn't see any conclusive evidence for Israel being the perpetrator. But I find the fact that Israel is not considered a suspect in the STL is HIGHLY SUSPICIOUS!!! Anyone with little logic and knowledge in courts of law would say the same thing!
