From Time :

To many observers in the Western world, Hizballah, the Lebanese guerrilla group battling Israel, is a mere puppet of Iran. Some are convinced that Hizballah triggered the crisis on Tehran’s orders to divert world attention away from Iran’s controversial nuclear plans. But client states are not necessarily as docile as one might think. Just as Israel sometimes takes actions that surprise (and even displease) the U.S., Hizballah does things Iran has neither ordered up nor necessarily approves of.
