Iran and Israel have had no diplomatic relations since 1979, and modern relations are hostile. The relationship was cordial for most of the Cold War, but worsened following the Iranian Revolution and has been openly hostile since the end of the Gulf War in 1991. Iran's current government does not recognize Israel's legitimacy as a state and has called for its destruction; it views Palestine as the sole legitimate government of the historic Palestinian territories. Israel considers Iran a threat to the Middle East's stability and has targeted Iranian assets in assassinations and airstrikes. In 2025, the hostility escalated to an armed conflict.
In 1947, Iran was among 13 countries that voted against the United Nations Partition Plan for the British Mandate of Palestine. Two years later, Iran also voted against Israel's admission to the United Nations. However, Iran was the second Muslim-majority country to recognize Israel as a sovereign state after Turkey. After the 1953 coup d'état, which reinstalled the pro-Western leader Mohammad Reza Pahlavi as the shah of Iran, relations between the two countries significantly improved. After the Iranian revolution—in which Pahlavi was ousted and Iran's secular monarchy was replaced by an anti-Western Islamic republic—Iran severed diplomatic and commercial ties with Israel, although relations continued covertly during the Iran–Iraq War (1980–1988).
