Palestinian leader in Lebanon Ali Al-Yousufuv appeared on TV to explain that the Palestinians do not want peace with Israelis. He insists that all they want is to kill them and mutilate their bodies: ?We will rip out the Israelis' spleens and livers?.
During this interview he refers to the local Arabs who left the area to allow the armies of Arab countries (Syria, Iraq, Lebanon, Egypt and Jordan) to exterminate the Jews and take their lands and property. This was the war that the Arabs declared on the one-day-old state of Israel in 1948, known as Israel's War of Independence.
While Israel agreed to the UN partition plan and called for peace, the Arabs rejected it because they wanted to genocide the Jews and take their lands. Arab countries are the ones who called on the local Arabs to leave in order to allow the systematic extermination of the local Jews. They openly declared their intention to "push the Jews into the sea". Against all odds, Israel won and now the Arabs who call themselves "Palestinians" who immigrated to the neighboring countries still claim that the all of lands of Israel should belong to them.
They declared war and lost, most of them left voluntarily and moved to neighboring Arab countries which at that time opened their borders because they wanted to facilitate the systematic genocide of Jews. The problem of the "Palestinian refugees" belongs to the Palestinians themselves and the neighboring Arab countries who wanted war instead of peace.
