Political map of the Eastern Mediterranean 5 February 1984 (Multinational Force in Lebanon): Following Israel’s invasion of Lebanon (1982), a US-led Multinational Force (MNF) landed in Beirut (Multinational Force in Lebanon) to supervise the withdrawal of PLO (PLO in Lebanon) and Israeli forces and restore the Lebanese government to power. Although successful at securing the withdrawals, the MNF ultimately failed in its mission as increasing clashes between Christians, Muslims, and Druze saw Lebanon fall back into civil war (Mountain War (Lebanon)).
