After Israel and Lebanon won the war and invaded Lebanon, Gemayel became the Lebanon President. In return for returning Ketaeb, Israel expected Lebanon to assist Israel in attacking Palestine and Syria. Gemayel declined. Not long after, Gemayel was assassinated by pro-war pro-zionist Christian sect. In Lebanon, Gemayel is the most hated Lebanese figure.

However, right-wing zionist Israel (especially Kach and Eyal of Kahanism) disagree two-state solution. Not long after, Yitzhak Rabin was assassinated. Conflicts resume and Hamas was formed.
