Mission On June 6, 1982, the
Israel Defense Forces (IDF) initiated Operation "Peace for Galilee" and invaded Lebanon in order to create a 40 km buffer zone between the PLO and
Syrian forces in Lebanon and Israel. The Israeli invasion was tacitly approved by the U.S., and the U.S. provided overt military support to Israel in the form of arms and materiel. The U.S.' support for Israel's invasion of Lebanon taken in conjunction with U.S. support for Lebanese President
Bachir Gemayel and the
Lebanese Armed Forces (LAF) alienated many. Bachir Gemayel was the legally elected president, but he was a partisan
Maronite Christian and covert associate of Israel. These factors served to disaffect the
Lebanese Muslim and
Druze communities. This animosity was made worse by the
Phalangist, a right-wing, largely Maronite-Lebanese militia force closely associated with President Gemayel. The Phalangist militia was responsible for multiple, bloody attacks against the Muslim and Druze communities in Lebanon and for the 1982 atrocities committed in the PLO refugee camps,
Sabra and Shatila by
Lebanese Forces (LF), while the IDF provided security and looked on. The Phalangist militia's attacks on Sabra and Shatila were purportedly a response to the September 14, 1982, assassination of President-elect Bachir Gemayel.
Amine Gemayel, Bachir's brother, succeeded Bachir as the elected president of Lebanon, and Amine continued to represent and advance Maronite interests. All of this, according to British foreign correspondent
Robert Fisk, served to generate ill will against the MNF among Lebanese Muslims and especially among the
Shiites living in the slums of West Beirut. Lebanese Muslims believed the MNF, and the Americans in particular, were unfairly siding with the Maronite Christians in their attempt to dominate Lebanon. As a result, this led to artillery, mortar, and small arms fire being directed at MNF peacekeepers by Muslim factions. Operating under the
peacetime rules of engagement, MNF peacekeepers – primarily U.S. and French forces – used minimum
use of force as possible in order to avoid compromising their
neutral status. Until October 23, 1983, there were ten guidelines issued for each U.S. marine member of the MNF: • When on post, mobile or foot patrol, keep loaded magazine in weapon, bolt closed, weapon on safe, no round in the chamber. • Do not chamber a round unless instructed to do so by a commissioned officer unless you must act in immediate self-defense where deadly force is authorized. • Keep ammo for crew-served weapons readily available but not loaded in the weapon. Weapons will be on safe at all times. • Call local forces to assist in self-defense effort. Notify headquarters. • Use only minimum degree of force to accomplish any mission. • Stop the use of force when it is no longer needed to accomplish the mission. • If you receive effective hostile fire, direct your fire at the source. If possible, use friendly snipers. • Respect
civilian property; do not attack it unless absolutely necessary to protect friendly forces. • Protect innocent civilians from harm. • Respect and protect recognized medical agencies such as
Red Cross,
Red Crescent, etc. The perimeter guards at the U.S. Marine headquarters on the morning of October 23, 1983, were in full compliance with rules 1–3 and were unable to shoot fast enough to disable or stop the bomber (see
Bombings: Sunday, October 23, 1983 below). In 1982, the
Islamic Republic of Iran established a base in the Syrian-controlled Beqaa Valley in Lebanon. From that base, Iran's
Islamic Revolutionary Guard Corps (IRGC) "founded, financed, trained and equipped
Hezbollah to operate as a proxy army" for Iran. Some analysts believe the newly formed Islamic Republic of Iran was heavily involved in the bomb attacks and that a major factor leading it to orchestrate the attacks on the barracks was America's
support for Iraq in the
Iran–Iraq War and its extending of $2.5 billion in trade credit to Iraq while halting the shipments of arms to Iran. A few weeks before the bombing, Iran warned that providing armaments to Iran's enemies would provoke retaliatory punishment. On September 26, 1983, "the
National Security Agency (NSA) intercepted an Iranian diplomatic communications message from the Iranian intelligence agency, the Ministry of Information and Security (MOIS)," to its ambassador, Ali Akbar Mohtashemi, in Damascus. The message directed the ambassador to "take spectacular action against the American Marines." The intercepted message, dated September 26, would not be passed to the Marines until October 26: three days after the bombing. Much of what is now public knowledge of Iranian involvement in the bombings, such as the purported supply of
PETN by Iran and the suicide bomber's name and nationality, was not revealed to the public until the 2003 trial,
Peterson, et al v. Islamic Republic, et al. Testimony by Admiral James "Ace" Lyon's, U.S.N. (Ret), and FBI forensic explosive investigator Danny A. Defenbaugh, plus a deposition by a Hezbollah operative named Mahmoud (a pseudonym) were particularly revealing.
Incidents On July 14, 1983, a Lebanese Armed Forces patrol was ambushed by
Lebanese Druze militia elements and from July 15–17, Lebanese troops engaged the Shia Amal militia in Beirut over a dispute involving the eviction of Shiite squatters from a schoolhouse. At the same time, fighting in the Shuf between the LAF and Druze militia escalated sharply. On July 22,
Beirut International Airport (BIA), the headquarters of the
U.S. 24th Marine Amphibious Unit (24th MAU), was shelled with Druze mortar and artillery fire, wounding three U.S. Marines and causing the temporary closure of the airport. This incident significantly increased tensions between the Shia community in Lebanon and Israel. This by extension, worsened increased tensions with the US. ==Bombings: Sunday, October 23, 1983==
