The LCP was also active in the guerrilla warfare against Israel and its proxy militia, the South Lebanon Army (SLA), in southern Lebanon, after the Israeli invasion in 1982. During the invasion he created the Lebanese National Resistance Front together with Muhsin Ibrahim. LNRF was commanded by Elias Atallah. At later stages of the war, the LCP under Hawi allied with Syria, which had entered Lebanon in 1976, but was to stay in the country for nearly 30 years.
