people tend to forget that there plenty of political assasinations following the hariri murder, these suddenly stopped after the dawha accord in which hizbula gained more political power, so who ordered the assasinations to stop?? who has the know-how, the motive and safe havens in lebanon?? it is hizbullah, and yes of course they have all the motive in the world to eliminate hariri senior. It is no small matter that hizbula potentially becomes a terrorist organization officially (not in europe yet) let alone the strong potential of a sunni-sheea civil war in lebanon which would sooner or later spill into Syria one way or another.
