Introduction

Once allies in a complex and unstable Middle East, Iran and Israel’s relationship has shifted dramatically over the past several decades. From covert military cooperation and oil deals during the reign of Iran’s Shah to today's deadly standoffs, cyberattacks, and proxy wars — their history is one of trust shattered, secrets unearthed, and a silent war that has shaped the very structure of the region.

This story traces that transformation: a geopolitical fault line where diplomacy turned to espionage, and collaboration to confrontation.

1. A Forgotten Alliance: 1948–1979

In the early years after the creation of the State of Israel in 1948, Iran — under the rule of Shah Mohammad Reza Pahlavi — was one of the few Muslim-majority nations that maintained covert ties with Israel. The two nations found common ground in opposing Arab nationalism, particularly Egyptian President Gamal Abdel Nasser’s pan-Arabism.

In the shadows of diplomacy, Israeli military advisors and intelligence personnel operated freely in Tehran. Mossad and SAVAK (the Shah’s secret police) collaborated closely, often sharing intelligence on shared enemies like the Soviet Union or militant Arab regimes. Iranian oil quietly flowed into Israeli ports. In return, Israel helped train Iranian forces and shared agricultural and technical expertise.

This era of quiet cooperation — built on pragmatism, not ideology — would come to an abrupt and violent end in 1979.

2. The Islamic Revolution: A Turning Point

The Iranian Revolution of 1979 marked a seismic shift. Ayatollah Ruhollah Khomeini overthrew the Shah and established an Islamic Republic founded on anti-Western and anti-Zionist ideology.

Israel, once seen as a strategic partner, was now declared an "illegitimate regime" and "the Little Satan" (America being the “Great Satan”). The Israeli embassy in Tehran was shut down, and the Palestinian Liberation Organization (PLO) was welcomed in its place.

This ideological hostility, however, did not completely sever all ties. In the early 1980s, during the Iran–Iraq War, Israel secretly sold weapons to Iran through the Iran–Contra Affair, seeing Iran as the lesser of two evils compared to Saddam Hussein’s Iraq. But this covert aid didn’t last. As Iran began supporting anti-Israel groups like Hezbollah, the shadow war truly began.

3. Rise of the Shadow War: 1990s–2000s

In the decades that followed, Iran emerged as a key backer of anti-Israeli proxy forces. Through Hezbollah in Lebanon, Hamas in Gaza, and various Shia militias, Iran worked to apply pressure on Israel’s borders without direct confrontation.

In return, Israel began a series of clandestine operations aimed at slowing or sabotaging Iran’s nuclear ambitions. The international community feared that Iran’s uranium enrichment program could be used to build nuclear weapons — a red line Israel vowed never to allow.

Mysterious explosions rocked Iranian military sites. Top nuclear scientists were assassinated in broad daylight. Iran blamed Israel and Mossad — claims often left unconfirmed but widely believed to be true.

The battlefield expanded. The war was now being fought in labs, deserts, and dark corridors of cyber networks.

4. Cyber Warfare and Espionage: 2010–Present

The nature of modern conflict evolved. The 2010 discovery of Stuxnet, a cyber weapon that disabled thousands of Iranian centrifuges at the Natanz nuclear facility, marked a new era. Believed to be a joint U.S.-Israeli operation, it was the first known virus designed to cause physical damage.

Iran retaliated with its own cyberattacks, targeting Israeli infrastructure, water systems, and private companies. The battlefield was now digital — and global.

Simultaneously, Israel continued launching airstrikes on Iranian targets in Syria, where Iran was building military outposts and weapons facilities. Iran denied, deflected, and doubled down.

The assassination of Mohsen Fakhrizadeh, Iran’s top nuclear scientist in 2020 — allegedly using a remote-controlled machine gun — stunned the world. Tehran vowed revenge. Israel remained silent, yet prepared.

5. Nuclear Brinkmanship and Diplomatic Stalemates

At the heart of the Iran-Israel conflict lies the nuclear question. Iran insists its nuclear program is peaceful. Israel, haunted by the memory of the Holocaust and wary of Iranian threats to “wipe Israel off the map,” considers a nuclear Iran an existential threat.

Years of diplomacy, particularly the 2015 Joint Comprehensive Plan of Action (JCPOA), gave brief hope. But when the U.S. withdrew from the deal in 2018, tensions spiked again.

Israel began warning of pre-emptive strikes. Iran enriched uranium beyond JCPOA limits. The Middle East once again teetered on the edge.

6. The People Left Behind

Behind every strike, every drone, and every threat of war, lie millions of civilians — Iranian and Israeli alike — caught in a geopolitical nightmare not of their making. Stories rarely told: families separated by ideology, students longing for peace, spies questioning their duty, and soldiers trained to kill people they’ll never meet.

Though leaders on both sides remain entrenched in hostility, a silent majority yearns for peace.

Conclusion: The Cracked Future

The history between Israel and Iran is not just one of conflict — it is a cautionary tale of how alliances can become rivalries, and how ideology can override diplomacy. With nuclear stakes, advanced cyber weapons, and deeply entrenched proxy networks, the Iran-Israel conflict is no longer just regional — it’s global.

But within this history lies a question: Can these two former allies ever find a path back from the brink? Or will the cracked map that divides them — as seen in the image — continue to fracture the region, one secret war at a time?
