Israel's role in the Iran–Iraq War consisted of support provided by Israel to Iran during the Iran–Iraq War from 1980 to 1988. During the war, Israel was one of the main suppliers of military equipment to Iran. Israel also provided military instructors during the war and direct support to Iran's war effort, when it bombed and destroyed Iraq's Osirak nuclear reactor, during Operation Opera. The nuclear reactor was a central component of Iraq's nuclear weapons program.
