The United States may have believed that it could accomplish in 2026 in Iran what it did in Iraq in 2003. When the United States attacked Iraq in 2003, it only took 26 days of intensive military operations to decimate Saddam Hussein's military. However, someone in Iran had meticulously studied the 2003 Iraq war and was determined to prevent the Iranian regime from collapsing like Saddam's did. That individual was Major General Mohammad Ali Jafari, the former commander-in-chief of the Islamic Revolutionary Guard Corps (IRGC).
On February 28, 2026, US and Israeli forces launched Operation Epic Fury, a massive decapitation assault including jets, drones, and precision missiles aimed against Iran's highest command levels.The strikes killed Supreme Leader Ayatollah Ali Khamenei, IRGC Commander-in-Chief Major General Mohammad Pakpour, Defense Minister Brigadier General Aziz Nasirzadeh, Armed Forces Chief of Staff Lieutenant General Seyyed Abdolrahim Mousavi, and other top officials.
According to a report by the Institute for the Study of War, the goal of these strikes was to disrupt Iran's command-and-control system and prevent retaliation. However, the collapse that the United States and Israel anticipated never occurred. It's been nearly two weeks, and Iran is still firing at will, threatening the entire Middle East.

That is conceivable for Iran since Mohammad Ali Jafari developed the concept of "Decentralised Mosaic Defence". The policy, designed to safeguard Iran's ability to fight even if its leadership is eliminated, distributes authority across semi-independent divisions capable of carrying out pre-established plans.
Iran's retaliation began almost immediately following the February 28 joint strikes. Within hours, salvos of ballistic missiles and drones pounded US military facilities in Bahrain, Qatar, the UAE, Kuwait, and Jordan, while strikes also hit targets within Israel and allied Gulf infrastructure. Despite President Masoud Pezeshkian's apology for bombing neutral states such as Oman and Bahrain, as well as assurances to respect Gulf state sovereignty, the barrages continued unabated, with attacks continuing as the war entered Day 14 on March 13.

This quick, sustained counterattack confounded predictions of collapse. Seyed Abbas Araghchi, Iran's Foreign Minister, described Iran's defense plan in a post on March 1. He stated, "We have had two decades to study the defeats of the US military to our immediate east and west. We've implemented lessons properly. Bombings in our capital have no bearing on our ability to conduct warfare. "Decentralised Mosaic Defence allows us to decide when and how the war will end."
Araghchi also stated that Iran's military forces had become "independent and somewhat isolated," operating under pre-established general directives.
Major General Mohammad Ali Jafari is the architect of Iran's "Decentralised Mosaic Defence," having spent years rewriting the country's military doctrine to ensure it could continue fighting even after losing its top leadership.The Mosaic Doctrine may not make Iran triumphant, but it makes failure unthinkable.

Who is Major General Muhammad Ali Jafari?
General Jafari is an Iranian military officer who began his career in the IRGC in an intelligence unit operating in Iran's Kurdistan province following the Islamic Revolution, which deposed the Pahlavi Dynasty, according to a RAND Organisation research from 2013.
Jafari fought in the Iran-Iraq War, which lasted from 1979 to 1989, gradually ascending through the ranks. Following the conflict, he was given general commander of the IRGC ground forces in 1992, as well as the Sarallah, an elite IRGC unit entrusted with defending Tehran.
In 2005, he was appointed director of the Guards' Center for Strategic Studies.

WHAT ARE THE LESSONS WHICH JAFARI DREW ON TO CREATE THE MOSAIC DOCTRINE?

According to a 2010 report by the US Institute of Peace, Iran's Mosaic Defence Doctrine draws upon the country's experience in the Iran-Iraq war (in which its authors fought), as well as observations from the US invasion of Iraq in 2003.The Iran-Iraq conflict was essentially a long battle of attrition in which the Iraqis launched a ground invasion of Iran, used chemical weapons against Iranian troops, and launched missile attacks on Iranian cities. In response, Tehran launched massive human wave attacks on Iraqi soldiers, particularly with its ideologically motivated, mass-mobilized Basij paramilitary forces.
According to the Institute of Peace, this allowed Iran to sustain casualties while also grinding the superior Iraqi forces into a stalemate that they could not break. This method of avoiding loss by generating extended attrition against a stronger invading army is a key component of the Mosaic Doctrine.Jafari has conducted extensive research on the United States' 2003 invasion of Iraq. According to a RAND Organisation analysis, Iraqi forces in 2003 were paralyzed by a command system centred on Iraqi tyrant Saddam Hussein.
According to the study, this prevented both regular Iraqi Army and Republican Guard units from coordinating with one another, while officers at the Division and Corps levels were unable to perform even basic exercises without Saddam's approval.
As a result, Iraqi forces, unable to operate independently, failed to adequately respond to the US-led Coalition assault, which overpowered all resistance on the path to Baghdad.

According to the 2010 report, the rapid defeat of Saddam Hussein's regime made Jafrai and other Iranian officials realise the importance of ensuring that the IRGC and regular Iranian armed forces (the Artesh) could operate independently without interference and would not fall apart if they lost contact with higher command.
What is the Mosaic doctrine developed by Mohammad Ali Jafari?
According to the RAND Organization, Iran's Mosaic Doctrine was first formulated in 2005, when Jafari, the director of the IRGC's Center for Strategic Studies, identified two critical threats to the Ayatollahs' regime: "a foreign attempt to foment a'soft revolution' through support of Iranian NGOs and activists and a US military attack that could topple the regime."Iran began adopting the theory in 2005, which accelerated after Jafari was appointed Commander-in-Chief of the IRGC in 2007. According to a 2010 US Institute of Peace research, the IRGC announced in 2005 that it was implementing a flexible, layered defense, known as a mosaic defense, into its doctrine. General Mohammad Jafari, then-director of the IRGC's Center for Strategy and eventually commander of the IRGC, was the primary creator of this plan.
According to a Soufan Centre analysis, the Mosaic Doctrine's approach emphasized multilayer, scattered defences to leverage Iran's topography, steep mountains, huge interior, and separated population centers, allowing for long-term resistance against superior invaders.

The key innovation was the IRGC's restructure into 31 semi-autonomous provincial commands (one per province, with the capital of Tehran left out). Each command functions independently, with its own headquarters, command-and-control nodes, missile and drone arsenals, integrated Basij militia formations, fast-attack marine flotillas, intelligence assets, stored armaments, and pre-delegated authority for crisis operations.
After taking command of the IRGC in 2007, Jafari oversaw its complete implementation, including the integration of Basij units and the enhancement of asymmetric capabilities.
This decentralisation, sanctioned by the late Supreme Leader Khamenei, gives local commanders extensive discretion to carry out broad objectives without real-time central monitoring.This resembles mission-type tactics, such as the German Auftragstaktik Doctrine, which, according to US Naval Institute study, allows subordinate officers to operate how they see fit as long as they accomplish pre-defined objectives set by their higher officers.

The Mosaic Doctrine in Action in the 2026 Iran-Israel-United States War
The mosaic defense doctrine was activated as planned during the 2026 Ramadan War, as Tehran refers to the battle between the United States and Israel. Despite Iran's clerical and military leadership being decimated in the first hours of the war on February 28, the country's 31 autonomous military commands retaliated within hours, striking US and Israeli military assets as well as civilian infrastructure such as airports, oil refining facilities and terminals, desalination plants, and others in Gulf countries such as the UAE, Qatar, Saudi Arabia, Bahrain, and Oman.

Farzin Nadimi, a defense specialist at the Washington Institute, told Radio Free Europe/Radio Liberty on March 3 that "every province is a mosaic, and commanders have the ability and power to make decisions." So, even if they are cut off from their command in Tehran, they can continue to function as a unified military force." Despite the decapitation of the leadership, this has allowed Tehran to continue its missile and drone campaigns, as well as regional escalation.
As Australian author Shanaka Anslem Perera wrote on X, "Iran is not on a suicide mission. It is on autopilot," adding that the "Mosaic Doctrine was not designed to win. It was intended to make defeat impossible. Jafari investigated how centralised armies die. He created one that cannot.

While the IRGC's ideological zeal and Tehran's missile drone stockpiles contribute to resilience, it was Jafari's Mosaic Doctrine, based on Iran's experience in the war against Iraq and his observation of the 2003 Iraqi defeat, that enabled Iran's deliberate, hydra-like endurance, forcing adversaries into a costly, protracted engagement rather than a quick victory. It insures that Iran cannot lose.
