On June 5, 1967, Israel launched a war against three neighboring countries, Palestine, Jordan, Syria, and Egypt.
The reasons for this war are due to several events, including Egypt's demand to withdraw the United Nations forces from the Sinai and the Egyptian army mobilized in it, and Egypt to close the Straits of Tiran (the waterway between the Gulf of Aqaba and the rest of the Red Sea) in the face of Israeli navigation, which Israel considered a declaration of war against it.
Among the causes of the war are also the armament efforts that Egypt was making during the era of the late President Gamal Abdel Nasser, and the founding of the Palestine Liberation Organization.
The war lasted from June 5 until June 10, then the Security Council issued Resolution No. 236 condemning any movement of forces after this date. Here, what it controlled expanded three and a half times what it controlled in 1948, making it about 80,000 km Square of Arab lands; Sinai, the Golan Heights, the Gaza Strip, and the West Bank, including East Jerusalem.
