In the early hours of June 13, 2025, Israeli fighter jets cross into Iranian airspace. What the world does not see is what happened before they took off. Across Tehran and its surroundings, at least twelve Mossad teams — Iranian-born agents trained in Israel and armed with rockets and explosives — have spent hours disabling air defense systems, one by one. Only then does the first wave of Israeli warplanes strike. The so-called 12-Day War has begun.

The trigger: Iran’s nuclear program. For years, the Islamic Republic had been inching closer to weapons-grade uranium. Israel’s window of opportunity had narrowed to weeks. Behind the assault lies years of covert preparation. The Mossad had spent decades building a network of agents inside Iran. Men and women who, driven by personal loss, hatred of the regime, or quiet conviction, had crossed over to the other side. Trained in secret, equipped as combat operatives, they represent a new kind of intelligence asset: what Mossad insiders call “agent-warriors.” In coordinated strikes, leading nuclear scientists and senior military commanders are eliminated. When Israel’s bunker-busting bombs cannot reach Iran’s deepest underground facilities, the United States enters the war.

After twelve days, US President Donald Trump orders a halt. The regime survives. Iran’s nuclear program is damaged, but not destroyed. And the anger of the Iranian people has nowhere left to go.

In January 2026, millions take to the streets across more than 400 cities — encouraged by Trump’s promise that “help is on the way.” The help never comes. Instead, Revolutionary Guards open fire on unarmed civilians. Hospitals are stormed. Doctors are arrested for treating the wounded. In a single night, tens of thousands are killed. It is the deadliest crackdown the Islamic Republic has ever unleashed on its own people.

On February 28, 2026, Israel strikes again — this time killing Supreme Leader Ayatollah Ali Khamenei. A second war begins. The regime survives that too.

Through testimonies from Mossad agents whose identities remain hidden, former CIA and CENTCOM officials, and Iranian civilians who lived through the massacre, ‘ Shadow Warriors – The Mossad’s Secret War in Iran’ reconstructs the full arc of a conflict that redefined the limits of covert warfare and shows what happens when a regime proves it will do anything to stay in power.
