Why can't Lebanon just get free of Hezbollah and live in harmony with Israel?

After all war between Israel and Hezbollah, the same question comes back: why don't the Lebanese authorities just disarm this organization? The answer is much more complex than the headlines suggest. Hezbollah is besides an armed organization, a legal political organization and 1 of the pillars of the Lebanese social system. Therefore, knowing his position requires looking not only at the conflict with Israel, but besides at the history, politics and weakness of Lebanon itself.
