A leading Lebanese academic has spoken of his feelings of déjà vu as Israel admits it has launched what it calls a limited ground operation in the south of Lebanon. Karim Emile Bitar is professor at Saint Joseph University of Beirut and at Sciences Po University in Paris. He says that from experience, Israel mostly manages to destroy its enemies when it enters into Lebanon, but is never able to bring stability to its northern border, and it’s the Lebanese people who pay the price. He spoke to us in Perspective.
