....hmm... Hariri was a 60 year old self-made billionaire, which means he likely made much of his fortune during a very bloody and turbulent period in Lebanese history. I have a Lebanese friend who says that corruption is widespread in the country and that in order for anything to get done bribes are required. Under these conditions, it's hardly surprising if Hariri made a lot of enemies.
I think the "rival business associate-shady business dealings" theory is the most convincing explanation for what happened...
I don't beleive in this theory at all, this guy was a self made billionaire not from Lebanon but from Saudi Arabia and he was the one that paid all the expenses for all the partys to attend the Taef Accord. The late Mr. Hariri was very clean and honest person, he was involved in lot of charity association and was helping people left and right.
