It’s hard to imagine now. If you flip on the news today, you see missiles, cyberattacks, and incredibly tense rhetoric. But there was a time—not even that long ago in the grand scheme of the Middle East—when things were totally different. Honestly, Israel and Iran used to be "peripheral" allies. They had a common enemy in the Arab world and a shared interest in survival.
Israel and Iran history isn’t just a timeline of hate. It’s a story of a messy, pragmatic breakup.
Before the 1979 Revolution, Iran was actually the second Muslim-majority country to recognize Israel. This was back in 1950. It wasn't a full, warm embrace, but it was a solid "de facto" recognition. The Shah, Mohammad Reza Pahlavi, saw Israel as a useful partner. Why? Because the Arab nations surrounding them weren't exactly friendly to Tehran either. It was a classic "the enemy of my enemy is my friend" situation.
The "Periphery Doctrine" and the Golden Era
David Ben-Gurion, Israel's first Prime Minister, had this strategy called the Periphery Doctrine. Basically, since the immediate Arab neighbors wanted Israel gone, Israel needed to find friends on the outside edges of the Middle East. That meant Turkey, Ethiopia, and most importantly, Iran.
You’ve got to realize how deep this went.
In the 1960s and 70s, Israeli construction companies were all over Tehran. They helped build the city’s infrastructure. Iranian oil kept the lights on in Tel Aviv. There was even a joint project called the Eilat-Ashkelon pipeline, designed to transport Iranian oil to the Mediterranean. It was a massive business deal. Military intelligence flowed freely between the Mossad and SAVAK (the Shah’s secret police). They were sharing secrets on everything from Soviet influence to Iraqi military movements.
It was a cold, hard alliance based on mutual benefit. No one was pretending to be best friends for the sake of it. It was about security. The Shah sold oil to Israel when no one else would. Israel provided technical expertise and weapons systems that the Shah desperately wanted to modernize his military.
Then 1979 Changed Everything
The Iranian Revolution wasn't just a domestic regime change. It flipped the regional chessboard upside down. When Ayatollah Khomeini took power, the ideology shifted from Persian nationalism to pan-Islamic leadership. To lead the Islamic world, Khomeini decided he needed to take the hardest possible line against Israel.
Suddenly, the "Little Satan" (Israel) and the "Great Satan" (the United States) became the primary targets of the new Republic’s ire.
But here is the weird part that most people forget. Even after the revolution, the transition to total enemies wasn't instant. During the Iran-Iraq War in the 1980s, Israel actually sold weapons to Iran. It sounds crazy now, right? But Saddam Hussein’s Iraq was seen as the bigger, more immediate threat to Israel at the time. Israel sent spare parts for F-4 and F-5 fighter jets to Tehran. They wanted to make sure Iran didn't lose too quickly to Iraq.
Pragmatism dies hard.
The Shift to a "Shadow War"
By the 1990s, the common threat of Iraq began to fade, especially after the Gulf War. This is where the Israel and Iran history we recognize today really starts to solidify. Without a shared enemy, the ideological divide became the main event. Iran began heavily funding and training proxy groups like Hezbollah in Lebanon.
Hezbollah’s primary goal was resisting the Israeli occupation of Southern Lebanon. This created a direct frontline between the two powers, even though they don't share a physical border.
Think about the 2000s. The tension shifted to the nuclear stage. Israel views a nuclear-armed Iran as an existential threat. Period. There’s no wiggle room there. On the flip side, Iran sees its nuclear program as a matter of national sovereignty and a deterrent against Western-backed regime change. This led to years of "gray zone" warfare. We’re talking about the Stuxnet virus—a piece of code that physically destroyed Iranian centrifuges—and the targeted assassinations of Iranian nuclear scientists like Mohsen Fakhrizadeh.
Misconceptions About the Conflict
A lot of people think this is a religious war that has been going on for thousands of years. It’s not.
Ancient history actually tells a different story. Cyrus the Great, the Persian King, is a hero in Jewish tradition because he freed the Jews from Babylonian captivity and let them rebuild their temple in Jerusalem. For centuries, Jews lived relatively peacefully within the Persian Empire. This current era of extreme hostility is a modern political development. It’s about power, regional hegemony, and the survival of regimes.
It’s also not a monolith. Within Iran, there is a massive generational divide. Many younger Iranians, who are more connected to the world via social media and VPNs, don't necessarily share the government's obsession with destroying Israel. They are more concerned with inflation, unemployment, and personal freedoms. Meanwhile, the hardliners in the IRGC (Islamic Revolutionary Guard Corps) view the "resistance" against Israel as the core pillar of their identity.
Why the Status Quo is Fragile
We are now in an era of direct confrontation. For decades, it was all about proxies. If Iran wanted to hit Israel, they used Hezbollah or Islamic Jihad. If Israel wanted to hit Iran, they used cyberattacks or covert ops.
That changed in April 2024. For the first time, Iran launched a massive direct drone and missile attack from its own soil toward Israel. Israel responded with its own targeted strike near Isfahan. The "shadows" are gone. The war is out in the open.
Current experts like Trita Parsi or analysts at the Institute for National Security Studies (INSS) point out that we are in a dangerous feedback loop. Each side feels they must retaliate to maintain "deterrence." But deterrence is a slippery thing. What one side calls a "measured response," the other side sees as an escalation that demands a bigger reply.
Actionable Insights for Following the Conflict
Understanding the depth of this history helps you see past the daily headlines. If you want to keep a pulse on where this is going, stop looking for "peace" and start looking for "de-escalation."
- Watch the Proxies: Any movement by Hezbollah in Lebanon or the Houthis in Yemen is usually a signal from Tehran. Iran uses these groups to put pressure on Israel without triggering a full-scale regional war that might involve the U.S.
- Monitor the Nuclear Threshold: The "breakout time"—how long it would take Iran to produce enough weapons-grade uranium for a bomb—is the ultimate red line. If that time drops to zero, the risk of a massive Israeli preemptive strike skyrockets.
- Follow Internal Iranian Stability: The more the Iranian government feels threatened by internal protests, the more likely they are to use external "enemies" like Israel to rally nationalist sentiment.
- Look at Regional Shifts: Keep an eye on the Abraham Accords. As more Arab nations like the UAE or potentially Saudi Arabia normalize ties with Israel, Iran feels increasingly encircled. This can lead to more aggressive posturing to prove they aren't being sidelined.
The history of these two nations is a reminder that in geopolitics, nothing is permanent. Alliances shift. Ideologies evolve. The tragedy of the current Israel and Iran history is that two nations that once found immense value in cooperation are now locked in a cycle that threatens the entire globe. Understanding the pragmatic roots of their past relationship is the only way to accurately interpret the volatility of their present.
To stay informed, look for reports from the International Crisis Group or the Carnegie Endowment for International Peace. They tend to provide the nuance that standard 24-hour news cycles miss. Focus on the maps and the technical reports on nuclear enrichment rather than just the fiery speeches from politicians. The real moves happen in the dark, long before they reach a podium.
