Hezbollah was largely formed with the aid of the Ayatollah Khomeini's followers in the early 1980s in order to spread Islamic revolution and follows a distinct version of Islamic Shi'a ideology (Valiyat al-faqih or Guardianship of the Islamic Jurists) developed by Ayatollah Ruhollah Khomeini, leader of the “Islamic Revolution” in Iran.
Although Hezbollah originally aimed to transform Lebanon into a formal Faqihi Islamic republic, this goal has been abandoned in favor of a more inclusive approach.
As of 2010, the Israeli government believed Hezbollah had an arsenal of more than 15,000 long-range rockets stationed on its border with Lebanon. Some of these missiles were said to be capable of penetrating cities as far away as Eilat.
The Israeli Ambassador to United States Michael Oren expressed deep concern with the revelation.
The Syrian-Iranian backed Hizbullah poses a very serious threat to Israel...Hizbullah today now has four times as many rockets as it had during the 2006 Lebanon war. These rockets are longer-range. Every city in Israel is within range right now, including Eilat.
The IDF has accused Hezbollah of storing these rockets beneath hospitals, schools, and civilian homes.
Since 1992, the organisation has been headed by Hassan Nasrallah, its Secretary-General.
