Iran–Israel relations
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.
Since 1985, Iran and Israel have been engaged in a proxy conflict that has greatly affected the geopolitics of the Middle East. The turn from cold peace to open hostility began in the early 1990s, shortly after the collapse of the Soviet Union and the defeat of Iraq in the Gulf War. Israeli prime minister Yitzhak Rabin's government adopted a more aggressive posture on Iran, and Iranian president Mahmoud Ahmadinejad made inflammatory statements against Israel. Other factors contributing to the escalation of tensions include the Iranian nuclear program, Iran's funding of Islamist groups such as Hezbollah, Palestinian Islamic Jihad, Hamas, and the Houthis, and Iran's involvement in attacks such as the 1992 Buenos Aires Israeli embassy bombing and the 1994 AMIA bombing, as well as Israeli threats of military action.
Iranian and Israeli organizations have been involved in direct military confrontations, such as in the 2006 Lebanon War. Iran and Israel have provided support for opposing factions in the Syrian and Yemeni civil wars and conducted cyberattacks and sabotage against each other's infrastructure, including attacks on nuclear facilities and oil tankers. Iran's proxy conflict with Saudi Arabia has led to an informal alliance between Israel and Arab states. In 2024, amid increasing regional tensions stemming from the Gaza war, Iran–Israel tensions escalated to a period of direct conflict; both carried out missile strikes on the other and Israel assassinated targets in Iran and Syria. In 2025, Israel carried out strikes against Iranian nuclear and military targets, sparking the 12 day long Iran–Israel war.
Timeline
Pre-modern background
The beginnings of Jewish history in Iran dates from late Biblical times. The biblical books of Isaiah, Daniel, Ezra, Nehemiah, Chronicles, and Esther contain references to the life and experiences of Jews in Persia. In the book of Ezra, the Persian king Cyrus the Great is credited with permitting and enabling the Jews to return to Jerusalem and rebuild their Temple; its reconstruction was carried out "according to the decree of Cyrus, and Darius, and Artaxerxes king of Persia". This is said to have taken place in the late sixth century BC, by which time there was a well-established and influential Jewish community in Persia. Persian Jews have lived in the territories of today's Iran for over 2,700 years, since the first Jewish diaspora when Shalmaneser V conquered the Kingdom of Israel and sent the Israelites into captivity at Khorasan. In 586 BC, the Babylonians expelled large populations of Jews from Judea to the Babylonian captivity. Jews who migrated to ancient Persia mostly lived in their own communities.The Jewish Bible's Ketuvim ends in Second Chronicles with the decree of Cyrus, which returned the exiles to the Promised Land from Babylon along with a commission to rebuild the temple.
'Thus saith Cyrus, king of Persia: All the kingdoms of the earth hath Yahweh, the God of heaven, given me; and He hath charged me to build Him a house in Jerusalem, which is in Judah. Whosoever there is among you of all His people—may Yahweh, his God, be with him—let him go there.'
This edict is also fully reproduced in the Book of Ezra.
"In the first year of King Cyrus, Cyrus the king issued a decree: 'Concerning the house of God at Jerusalem, let the temple, the place where sacrifices are offered, be rebuilt and let its foundations be retained, its height being 60 cubits and its width 60 cubits; with three layers of huge stones and one layer of timbers. And let the cost be paid from the royal treasury. Also let the gold and silver utensils of the house of God, which Nebuchadnezzar took from the temple in Jerusalem and brought to Babylon, be returned and brought to their places in the temple in Jerusalem; and you shall put them in the house of God.'
As a result of Cyrus's policies, the Jews honored him as a dignified and righteous king. There is no evidence that the declaration reflected a unique attitude toward Jews. Rather, it may have been part of his renowned tolerance toward the cultures and religions of the people under his rule. The historical nature of this decree has been challenged. Professor Lester L Grabbe argues that there was no decree but that there was a policy that allowed exiles to return to their homelands and rebuild their temples. He also argues that the archaeology suggests that the return was a "trickle", taking place over perhaps decades, resulting in a maximum population of perhaps 30,000. Philip R. Davies called the authenticity of the decree "dubious", citing Grabbe and adding that J. Briend argued against "the authenticity of Ezra 1.1–4 is J. Briend, in a paper given at the Institut Catholique de Paris on 15 December 1993, who denies that it resembles the form of an official document but reflects rather biblical prophetic idiom".
Mary Joan Winn Leith believes that the decree in Ezra might be authentic and along with the Cylinder that Cyrus, like earlier rules, was through these decrees trying to gain support from those who might be strategically important, particularly those close to Egypt which he wished to conquer. He also wrote that "appeals to Marduk in the cylinder and to Yahweh in the biblical decree demonstrate the Persian tendency to co-opt local religious and political traditions in the interest of imperial control".
According to the Bible, Cyrus ordered rebuilding the Second Temple in the same place as the first; he died before it was completed. Darius the Great came to power in the Persian empire and ordered the completion of the temple. According to the Bible, the prophets Haggai and Zechariah urged this work. The temple was ready for consecration in the spring of 515 BCE, more than twenty years after the Jews' return to Jerusalem.
According to the Book of Esther, during the reign of Persian King Ahasuerus, generally identified as Xerxes the Great in 6th century BCE, the vizier Haman instigated a plot to kill all the Jews of ancient Persia. The plot was thwarted by Queen Esther who ordered the hanging of Haman and his ten sons. This event is celebrated as the holiday of Purim.
Israeli independence to Iranian revolution (1947–1979)
In 1947, Iran was one of the 11 members that formed the Special Committee on Palestine charged to investigate the cause of the conflict in Palestine Mandate, and, if possible, devise a solution. After much deliberation the committee presented a Partition Plan for Palestine, which had the support of 8 of the 11 members of UNSCOP. Iran along with India and Yugoslavia opposed the plan, predicting it would lead to an escalation of violence. Arguing that peace could only be established through a single federal state, Iran voted against the partition plan when it was adopted by the UN General Assembly. Shah Mohammad Reza Pahlavi predicted that the partition would lead to generations of fighting.In Spring of 1948, 30,000 Iranians in Tehran gathered to protest against the establishment of Israel.

After the establishment of the State of Israel in May 1948, Israel and Iran maintained close ties. Iran was the second Muslim-majority country to recognize Israel as a sovereign state after Turkey. Israel viewed Iran as a natural ally as a non-Arab power on the edge of the Arab world, in accordance with David Ben Gurion's concept of an alliance of the periphery. Israel had a permanent delegation in Tehran which served as a de facto embassy, before Ambassadors were exchanged in the late 1970s.
After the Six-Day War, Iran supplied Israel with a significant portion of its oil needs and Iranian oil was shipped to European markets via the joint Israeli-Iranian Eilat-Ashkelon pipeline. Trade between the countries was brisk, with Israeli construction firms and engineers active in Iran. El Al, the Israeli national airline, operated direct flights between Tel Aviv and Tehran. Iranian-Israeli military links and projects were kept secret, but they are believed to have been wide-ranging, for example the joint military project Project Flower, an Iranian-Israeli attempt to develop a new missile.
Debts
As at 1979, Israel owed about a billion dollars to Iran for business conducted before the Iranian revolution. Some of the debt arose from oil purchased by Israel, and a larger amount from the operation of the Trans-Israel oil pipeline and associated port facilities, which were a joint venture between Israeli companies and the National Iranian Oil Company. Israel decided against paying the debt at a meeting in 1979 and granted legal indemnity to Israeli companies which owed it. At least one Israeli bank account is known to hold $250 million owed to Iran.Since the 1980s, Iran has been suing in the European courts for payment of the debts and has won several cases. Payment of the debts is legally complicated by the international sanctions against Iran and by the fact that Israel classifies Iran as an enemy state. In May 2015, a Swiss court ordered the Eilat Ashkelon Pipeline Company to pay $1.1 billion to Iran, which Israel refuses to do.
