If anyone is interested in the cause of the 1967 war.
To lazy to click? Here is a summary.
Suez Crisis
http://www.history.com/topics/cold-war/suez-crisis
Was an invasion of Egypt in late 1956 by Israel, followed by the United Kingdom and France. The aims were to regain Western control of the Suez Canal and to remove Egyptian President Gamal Abdel Nasser, who had just nationalized the canal. On 29 October, Israel invaded the Egyptian Sinai. Britain and France issued a joint ultimatum to cease fire, which was ignored. On 5 November, Britain and France landed paratroopers along the Suez Canal. The Egyptian forces were defeated, but they did block the canal to all shipping. It later became clear that the Israeli invasion and the subsequent Anglo-French attack had been planned beforehand by the three countries.
The Six Day War

After the 1956 Suez Crisis, Egypt agreed to the stationing of a United Nations Emergency Force (UNEF) in the Sinai to ensure all parties would comply with the 1949 Armistice Agreements. Despite the overwhelming support for Resolution 1000 in the UN General Assembly, Israel refused to allow UNEF forces onto its territory. In the following years, there were numerous minor border clashes between Israel and its Arab neighbors, particularly Syria. In early November, 1966, Syria signed a mutual defense agreement with Egypt. On November 13, 1966, in response to PLO (Palestine Liberation Organization) guerrilla activity, including a mine attack that left three dead, the Israeli Defence Force (IDF) attacked the village of as-Samu in the Jordanian-occupied West Bank. Jordanian units that engaged the Israelis were quickly beaten back. King Hussein of Jordan criticized Egyptian President Gamal Abdel Nasser for failing to come to Jordan's aid, and "hiding behind UNEF skirts". Israel was censured for this invasion in United Nations Security Council Resolution 228, being reproached by the US, the UK, France and the USSR. On April 7, 1967 Israel invaded Syria. The USSR urged that the collective defense agreement with Egypt had been triggered. In May 1967, Nasser received false reports from the Soviet Union that Israel was massing on the Syrian border.
Nasser began massing his troops in the Sinai Peninsula on Israel's border (May 16), expelled the UNEF force from Gaza and Sinai (May 19) and took up UNEF positions at Sharm el-Sheikh, overlooking the Straits of Tiran. Israel reiterated declarations made in 1957 that any closure of the Straits would be considered an act of war, or justification for war. Nasser declared the Straits closed to Israeli shipping on May 22–23. On May 30, Jordan and Egypt signed a defense pact. The following day, at Jordan's invitation, the Iraqi army began deploying troops and armored units in Jordan. They were later reinforced by an Egyptian contingent. On June 1, Israel formed a National Unity Government by widening its cabinet, and on June 4 the decision was made to go to war. The next morning, Israel launched Operation Focus, a large-scale surprise air strike that launched the Six-Day War.
Whether their actions are justified remains debatable today. I think none of them were in the right.
FYI: Territory disputes, and Regime Change does not equal genocide.
