No one has claimed responsibility for the car bomb that killed Hezbollah terrorist mastermind Imad Mugniyeh in Damascus yesterday. A well-connected source tells me that all signs point to it being an Israeli operation, a scenario which my colleague in Jerusalem, Chris Mitchell, also seems to be hearing. But don't expect the Israelis to claim credit--that isn't their style. Needless to say, Mugniyeh's assassination is a huge blow to the Hezbollah/Iran/Syria axis. Mugniyeh wore many hats within that axis, as our friend Walid Phares describes here. I've discussed Mugniyeh several times on CBN News programs, and blogged about his deadly exploits--which include his planning of the 1983 Marine barracks bombing in Beirut, which killed 243 U.S. Marines--here and here. He'd become an almost mythical figure due to his ability to elude capture and direct major terrorist attacks while living underground. He was one of the most--if not the most--influential terrorists of the past 30 years. The only bigger jihadi fish that could be nabbed would be Osama Bin Laden or Ayman al-Zawahiri, but only because they have greater symbolic value. But those two are basically figureheads, whereas Mugniyeh was an operational guy, and, therefore, much more dangerous. When it came down to the nuts and bolts of actually carrying out an operation, no one was more dangerous than Mugniyeh. America is a safer with him gone.
