Saddam Hussein visited Iran in 1976

When Egypt and Syria attacked Israel in the October 1973 war, Israel even asked the Iraqi Kurds to mount an offensive operation against Iraq in order to keep it from joining in that war. Upon consulting with the Americans, who then consulted with the Shah, about this request, the Kurds were convinced not to do so and to instead retain a defensive posture inside Kurdistan.
