In June 1967 Israeli troops marched into East Jerusalem, the West Bank, Gaza Strip, the Sinai Desert and the Golan Heights.
The Egyptian capital of Cairo and the Syrian capital of Damascus were now in range of Israeli artillery, with their troops 50 miles from the Syrian capital and overlooking the strategic Suez Canal.
The Six Day War dealt a huge blow to the regimes that arose out of a wave of popular revolutions against colonialism in the Middle East.
After 1967 these regimes turned against the movements that brought them to power, leading to Egypt recognising the Israeli state and making peace with imperialism. But it would also lead to a new resistance movement growing out of the refugee camps of Jordan and spreading to Lebanon and the Occupied Territories of Palestine.
Anne Alexander examines the impact of the war on Egypt and Arab nationalism. John Rose explains how the Israeli victory served US imperialism, and remembers the debates on the left that grew out of the war.
