When Sarkis effectively began to serve as the President, he could not forge a lasting accommodation between Christian and Muslim factions. Also, the growing independent power of the Palestinian guerrillas in Lebanon prompted two large-scale Israeli attacks, in 1978 and 1982. Several nationalist and leftist political parties and organizations created the Lebanese National Movement (LNM) under the leadership of Kamal Jumblatt in 1976. The conservative forces led by the Christian Kata'ib (Phalange) Party was another block called the Lebanese Front. President Sarkis tried various initiatives to find a negotiated settlement to the conflict, but all were unsuccessful. Because these two groups had their own goals. The Lebanese Front was gradually strengthened its position, awaiting favorable regional developments to impose its own will. The LNM, on the other hand, was too dependent on the Palestinians and unable to initiate a political negotiation process in ceasing the civil war. In November 1976, Sarkis wanted to include Druze za'im Kamal Jumblatt in the cabinet. However, Hafez Assad did not permit it due to Jumblatt's clear opposition to Syria's increasing influence in Lebanon.
