In 1982 , Israel decided to invade into Lebanon . in what was then called by the Israelis Operation Peace for Galilee , in order to root out Palestinian insurgents and support the Christian militias and the Free Lebanon State on the course of the Lebanese Civil War . Following the 1982-85 fighting , the IDF remained deployed in the area of southern Lebanon controlled by Lebanese Christian militias , which was declared by the Israelis as a security zone . Though most casualties on the course of consequent 1985-2000 conflict with Hezbollah were from the South Lebanon Army ranks , this deployment had claimed many casualties also from the IDF over the years . The most serious incident of IDF at the time being the helicopter disaster , which occurred on February 4 , 1997 killing 73 soldiers from the Nahal Brigade , armored and Engineering fighters ( 188 Brigade and Battalion 601 ) and the helicopter crew . Following the 1997 helicopter disaster , four women from Northern Israel , whom were mothers of soldiers who served in Lebanon , Rachel Ben Dor , Miri Sela , Ronit Nahmias and Zahara Antebi , decided to organize protest activities which will call for the unilateral and immediate withdrawal of Israeli forces from Lebanon . The purpose of the movement was to put public pressure on the Israeli government to withdraw from Lebanon , with or without a peace agreement , and thus to implement the United Nations Security Council Resolution 425 , calling for the recognition of the territorial integrity and sovereignty of Lebanon , for the IDF to leave the area and the deployment of an international force in the region . The movement ignored the South Lebanon Army-IDF alliance understandings in regard to Israeli support for the South Lebanon security zone administration , emphasizing the human life cost of the IDF deployment
