How the Iranian Revolution Transformed the Relationship with Israel - From Persia to Iran
A Biblical, Historical, and Prophetic Perspective
For Jewish readers, the relationship between Persia and Israel carries an extraordinary historical memory.
Persia is not merely a name on an ancient map. Persia appears throughout Jewish history as an empire that, at a critical moment, permitted the Jewish people to return to Jerusalem and rebuild the Temple. The Book of Esther takes place within the Persian Empire, and the prophets speak of Persian rulers in connection with God's purposes for Israel.
Yet the modern relationship between Israel and Iran looks radically different.
For much of the twentieth century, the government of Iran maintained discreet but substantial relations with Israel. Iran supplied Israel with oil, maintained commercial and military contacts, and shared strategic concerns about Arab nationalism and Iraq. Iranian-Israeli cooperation continued even though Iran had no formal diplomatic relationship with Israel.
Then came 1979.
The Iranian Revolution overthrew Shah Mohammad Reza Pahlavi and replaced the monarchy with an Islamic revolutionary government led by Ayatollah Ruhollah Khomeini. The revolution did not simply change Iran's leadership. It changed the ideological framework through which the Iranian state understood the United States, Israel, the Middle East—and Iran's own identity.
That transformation is the key to understanding why two countries that had quietly cooperated for decades became bitter adversaries.
Persia and Israel: A Remarkable Biblical Connection
The Bible presents ancient Persia in a surprisingly positive role at one of the most important turning points in Jewish history.
The prophet Isaiah names Cyrus, king of Persia, centuries before the Persian king's conquest of Babylon:
“Thus says the LORD to His anointed,
To Cyrus, whose right hand I have held...”
—Isaiah 45:1
Isaiah describes Cyrus as an instrument through whom God would accomplish a purpose connected with Jerusalem.
Isaiah 44:28 declares:
“He is My shepherd,
And he shall perform all My pleasure,
Saying to Jerusalem, ‘You shall be built,’
And to the temple, ‘Your foundation shall be laid.’”
The Book of Ezra then records the fulfillment of this historical moment. “In the first year of Cyrus king of Persia,” the biblical text says, God stirred Cyrus's spirit and Cyrus issued a proclamation concerning Jerusalem and the Temple.
For Jewish history, this is extraordinary.
Babylon had destroyed Jerusalem and the First Temple. Persia defeated Babylon. Cyrus then permitted Jewish exiles to return and rebuild.
The biblical narrative therefore gives us a powerful reminder:
A nation can play one role in one generation and a very different role in another.
The Persia of Cyrus cannot simply be equated with the Islamic Republic of Iran. Ancient Persia, the Pahlavi monarchy, and the Islamic Republic are different political and historical entities.
That distinction is essential.
The Pahlavi Era: When Iran and Israel Cooperated
Before 1979, Iran was ruled by the Pahlavi monarchy.
Under Shah Mohammad Reza Pahlavi, Iran became an important American ally and a major regional power. Iran also developed extensive unofficial relations with Israel.
A 1975 U.S. intelligence memorandum described Iranian-Israeli ties as remarkably stable. It documented cooperation in oil, agriculture, water resources, aviation, military affairs, and intelligence. Iran was also an important source of oil for Israel.
The relationship was not primarily based upon religious affection.
It was strategic.
Both governments had concerns about Arab nationalism, particularly the influence of Iraq. Iran also wanted to maintain relationships with Arab states while preserving its relationship with Israel. Consequently, Tehran's connection with Israel was often deliberately kept discreet.
This is an important lesson:
States do not necessarily form relationships because they share the same religion or culture. They frequently cooperate because their strategic interests overlap.
Iran and Israel were not natural ideological allies. But under the Shah, their governments found reasons to cooperate.
Then the foundations of Iranian foreign policy changed.
1979: The Revolution That Changed Everything
The Iranian Revolution of 1979 was not merely a change of government.
It was a transformation of political identity.
The Pahlavi monarchy was overthrown, and Ayatollah Ruhollah Khomeini emerged as the dominant revolutionary leader. The new Islamic Republic rejected the Shah's close relationship with the United States and rejected much of the political order associated with the Western-aligned monarchy. Contemporary U.S. historical records describe the revolution as producing fundamentally changed regional realities.
Israel was increasingly incorporated into this new revolutionary worldview.
Under the Shah, Israel had been viewed largely through the lens of Iranian strategic interests.
After the revolution, Israel increasingly became part of an ideological conflict.
That distinction explains much of the dramatic change.
From Strategic Cooperation to Ideological Opposition
The Islamic Republic's leadership did not simply inherit the Shah's foreign policy and adjust it.
It rejected many of its fundamental premises.
The revolutionary government defined itself in opposition to the influence of the United States and the political order associated with it. Israel, because of its close relationship with Washington and because of the Palestinian issue, became increasingly identified by revolutionary leaders as part of that opposing system.
The transformation therefore operated on several levels.
1. Iran's political identity changed
The monarchy had presented Iran as a modernizing Persian state closely connected to the West.
The Islamic Republic presented Iran as an Islamic revolutionary state.
That difference fundamentally changed foreign policy.
2. The Palestinian issue became central
Khomeini strongly identified the revolution with the Palestinian cause. U.S. intelligence assessments from 1979 noted Khomeini's explicit endorsement of the Palestinians and the effect that Iranian revolutionary ideology was having on regional politics.
3. Israel became an ideological adversary
Israel was no longer simply a country with which Iran had complicated strategic relations.
It became a symbol of the regional and international order the revolution opposed.
4. The American-Iranian relationship collapsed
The November 1979 seizure of the U.S. Embassy in Tehran and the hostage crisis dramatically demonstrated how completely Iran's relationship with the United States had changed. More than 50 Americans were held for 444 days, and the United States severed diplomatic relations with Iran in April 1980.
This mattered enormously for Israel because Israel's security relationship with the United States subsequently became even more important within the emerging regional alignment.
The Paradox of Modern Persia
Here we encounter a remarkable historical paradox.
The ancient Persian king Cyrus is remembered in Jewish Scripture for facilitating the return of Jewish exiles to Jerusalem.
The modern Islamic Republic of Iran has developed a state ideology profoundly hostile toward the State of Israel.
These realities appear contradictory only if we assume that "Persia" represents one continuous political personality.
It does not.
The Persian Empire of Cyrus, the later Persian kingdoms, the Pahlavi monarchy, and the Islamic Republic belong to very different historical periods.
The Bible itself demonstrates that empires rise and fall and that political power changes hands.
Daniel repeatedly presents kingdoms as temporary.
“He removes kings and raises up kings.”
—Daniel 2:21
That principle provides a useful biblical framework for thinking about Iran.
A government is not identical to a civilization.
And a regime is not identical to an entire people.
Persia, Israel, and the Book of Esther
For Jewish readers, perhaps the most emotionally powerful connection between Persia and Israel is the Book of Esther.
Esther takes place in the Persian Empire.
There, the Jewish people face an existential threat from Haman. The danger comes from within the political structure of Persia itself.
Yet the story ends with deliverance.
The Book of Esther does not describe a simple relationship between "Persia" and "the Jews." It shows something more complicated: Jews living inside a powerful Persian political system, vulnerable to the decisions of rulers and officials, while God's providence operates through events that initially appear uncertain.
This offers an important theological lesson for the present:
The identity of a government can change, but Jewish history cannot be understood solely by examining the government of the moment.
The Jewish people have lived under Persian, Greek, Roman, Islamic, European, and modern political powers.
Our security has never ultimately rested upon the permanence of one earthly regime.
A Prophetic Dimension: Persia in Ezekiel
For readers interested in biblical prophecy, the discussion becomes even more intriguing.
Ezekiel 38 names Persia among the nations associated with Gog's coalition:
“Persia with them...”
—Ezekiel 38:5
This verse has attracted enormous attention because modern Iran occupies much of the geographic territory associated with ancient Persia.
But caution is essential.
The biblical text does not explicitly say that the modern Islamic Republic of Iran is identical to the Persia mentioned in Ezekiel 38.
Nor does the passage provide enough information to establish a detailed modern military timetable.
What we can say is that Persia is explicitly named in an end-times passage concerning a future conflict involving Israel.
That makes the ancient Persian-Israel relationship particularly interesting for students of biblical prophecy.
Yet prophecy should produce watchfulness rather than certainty where Scripture itself does not provide certainty.
Could the Same Land Be Both a Friend and an Enemy?
From a biblical perspective, there is no contradiction in saying that Persia once served God's purposes for Israel while later Persian rulers could become hostile to Israel.
The Bible repeatedly demonstrates that God can use nations without endorsing everything those nations believe or do.
Cyrus himself is the clearest example.
God calls him His “anointed” in Isaiah 45:1, even though Cyrus was not an Israelite king.
Ezra records Cyrus's role in restoring Jerusalem and the Temple.
The theological implication is profound:
God's sovereignty is larger than the ideology of any particular government.
A government can change.
An empire can disappear.
A revolution can overturn a monarchy.
A new ideology can replace an old one.
But biblical prophecy teaches Jewish readers to look beyond the temporary political arrangement toward God's larger purposes.
What Actually Changed in 1979?
The simplest answer is this:
Iran's relationship with Israel changed because Iran's political identity changed.
Before 1979, the Shah's government approached Israel primarily through strategic, economic, military, and regional calculations.
After 1979, the Islamic Republic approached Israel increasingly through a revolutionary ideological framework in which opposition to Israel was tied to its broader rejection of the existing regional and international order.
The change was therefore deeper than a diplomatic disagreement.
It was a change in worldview.
The relationship moved roughly from:
Strategic cooperation → revolutionary opposition
and from:
Quiet pragmatic engagement → ideological confrontation
This is why the transformation was so dramatic.
But Iran Is More Than Its Government
There is another distinction Jewish readers should remember.
Iranian civilization is much older than the Islamic Republic.
Persian history stretches back thousands of years. Iranian culture, literature, language, art, and civilization cannot simply be reduced to the policies of the government established in 1979.
Likewise, the Iranian people should not automatically be equated with every policy or statement of the Iranian government.
This distinction is particularly important when considering the biblical relationship between Israel and Persia.
The Bible tells us about Persian kings.
It does not tell us that every Persian person throughout history is either friend or enemy of Israel.
Political regimes change.
Peoples endure.
Civilizations evolve.
A Jewish Prophetic Perspective
For Jewish readers, perhaps the most significant question is not simply:
“Is Iran our enemy?”
The more profound biblical question is:
“What does Scripture teach us about God's sovereignty when nations rise against Israel?”
The answer of the Hebrew Bible is remarkably consistent.
Nations may gather.
Kings may make plans.
Empires may rise.
Political identities may change.
But none of these developments occur outside God's sovereignty.
Psalm 2 asks:
“Why do the nations rage,
And the people plot a vain thing?”
And the prophet Zechariah declares:
“He who touches you touches the apple of His eye.”
—Zechariah 2:8
These passages should not be used to predict a specific contemporary military event. They speak more broadly to the biblical conviction that Israel's destiny cannot ultimately be separated from God's purposes.
The Great Historical Irony
There is an extraordinary irony in the history of Persia and Israel.
The Persian Empire once provided the political environment in which Jewish exiles returned to Jerusalem.
Centuries later, modern Iran became one of the most prominent state opponents of Israel.
Yet the biblical story reminds us that history is never static.
The Persia of Cyrus was not the Persia of Esther.
The Persia of Esther was not the Persia of later centuries.
The Persia of antiquity is not the Islamic Republic of Iran.
And the Islamic Republic of Iran will not necessarily remain unchanged forever.
That final observation is historical rather than predictive.
No modern government is eternal.
What Can Jewish Readers Take From This?
The history of Israel and Persia teaches several important lessons.
First, political alliances can change dramatically.
The Iranian-Israeli relationship before 1979 demonstrates how strategic interests can produce cooperation even between countries with significant cultural and political differences.
Second, revolutions can redefine national identity.
The Iranian Revolution transformed the framework through which Tehran understood its relationship with the United States, Israel, and the wider Middle East.
Third, ancient biblical Persia should not automatically be equated with modern Iran.
The biblical Persia existed within a completely different political, religious, and historical world.
Fourth, Scripture teaches Jewish readers to distinguish nations from regimes.
A government can act in opposition to Israel without every individual within that country sharing the government's worldview.
Finally, biblical prophecy calls for discernment.
Ezekiel's mention of Persia is significant, but it should not be transformed into a detailed modern political forecast that the biblical text itself does not provide.
From Cyrus to Khomeini—and Beyond
The story begins with Cyrus.
A Persian king becomes, in Isaiah's words, God's instrument in relation to Jerusalem. Ezra records the return of Jewish exiles and the rebuilding of the Temple.
It eventually reaches the Persian court of Esther, where the Jewish people survive another existential threat.
Then history moves through centuries of Persian and Islamic civilization.
Finally, in the twentieth century, the Pahlavi monarchy establishes a pragmatic relationship with Israel.
And in 1979, revolution transforms Iran's ideological identity.
The lesson is not that Persia is permanently destined to be Israel's friend—or permanently destined to be Israel's enemy.
The deeper biblical lesson is that God remains sovereign while kingdoms change.
Isaiah's message concerning Cyrus reminds us that God can accomplish His purposes through unexpected nations and rulers.
Esther reminds us that Jewish survival cannot be understood merely through the political calculations of the moment.
Ezekiel reminds us that Persia appears again in biblical prophecy—but leaves important questions about the timing and identity of future events.
And Jewish history reminds us that today's political reality is never necessarily tomorrow's.
Perhaps that is the most important prophetic lesson.
Israel must understand the nations, but Israel's ultimate hope cannot rest upon the nations.
As the Psalmist declares:
“Some trust in chariots, and some in horses;
But we will remember the name of the LORD our God.”
—Psalm 20:7
The history of Persia and Israel has passed through friendship, distance, cooperation, revolution, and confrontation.
History has changed.
Governments have changed.
Ideologies have changed.
But the biblical story continues to point Jewish eyes beyond the changing kingdoms of men—to the enduring sovereignty of God.
