Israel responds to an ominous build-up of Arab forces along its borders by launching simultaneous attacks against Egypt and Syria. Jordan subsequently entered the fray, but the Arab coalition was no match for Israel's proficient armed forces. In six days of fighting, Israel occupied the Gaza Strip and the Sinai Peninsula of Egypt, the Golan Heights of Syria, and the West Bank and Arab sector of East Jerusalem, both previously under Jordanian rule. By the time the United Nations cease-fire took effect on June 11, Israel had more than doubled its size. The true fruits of victory came in claiming the Old City of Jerusalem from Jordan. Many wept while bent in prayer at the Western Wall of the Second Temple.
The U.N. Security Council called for a withdrawal from all the occupied regions, but Israel declined, permanently annexing East Jerusalem and setting up military administrations in the occupied territories. Israel let it be known that Gaza, the West Bank, the Golan Heights, and the Sinai would be returned in exchange for Arab recognition of the right of Israel to exist and guarantees against future attack. Arab leaders, stinging from their defeat, met in August to discuss the future of the Middle East. They decided upon a policy of no peace, no negotiations, and no recognition of Israel, and made plans to defend zealously the rights of Palestinian Arabs in the occupied territories.
Egypt, however, would eventually negotiate and make peace with Israel, and in 1982 the Sinai Peninsula was returned to Egypt in exchange for full diplomatic recognition of Israel. Egypt and Jordan later gave up their respective claims to the Gaza Strip and the West Bank to the Palestinians, who opened "land for peace" talks with Israel beginning in the 1990s. A permanent Israeli-Palestinian peace agreement remains elusive, as does an agreement with Syria to return the Golan Heights.
