The Zagros Front

While the world watches the air campaign over Tehran, a ground war is opening in western Iran.

Thousands of Kurdish fighters from the Kurdistan Free Life Party (PJAK) began taking combat positions inside Iranian territory at midnight on March 2 — two days into the air campaign. Iranian forces evacuated the border city of Mariwan on March 3 and dug into defensive positions around the town. PJAK fighters are now deployed deep in the Zagros Mountains, the spine of western Iran.

From the other side, Baloch militant groups have crossed from Pakistan into southeastern Iran. Kurdish peshmerga in northern Iraq are on standby near the border in Sulaymaniyah province. This isn't one axis. It's three.

This is no longer just an air campaign. It's the opening chapter of a ground war — fought not by American soldiers but by ethnic insurgencies with American and Israeli backing.

The Playbook

The pattern is familiar. CNN reported the CIA is working to arm Kurdish forces to foment an uprising inside Iran. The Wall Street Journal says the Trump administration is open to supporting armed groups willing to challenge the regime. Trump personally called two Kurdish faction leaders earlier this week.

A US official told the Guardian that Washington is "ready to provide air support" if Kurdish peshmerga cross from Iraq. Israel's military confirmed the IAF has been "heavily operating in western Iran" to "degrade Iranian capabilities and open a way to Tehran." Dozens of military positions, frontier posts, and police stations along Iran's border with Iraq have been hit.

The infrastructure is there. Five rival Iranian Kurdish organizations — led by the Democratic Party of Iranian Kurdistan (KDPI) — formed a coalition just two weeks before the war started. "Getting your groups aligned and united is the first play in the playbook," a former US defense official told the Guardian.

This was not improvised. The Kurdish coalition formed weeks ago. Clandestine operations were "ramped up" after last summer's Twelve-Day War. This ground dimension was planned alongside the air campaign from the start.

The Model and Its Risks

It's the Syria model. Small teams of military or CIA specialists embed with locally recruited ground forces. Airpower provides the hammer; the insurgency provides the map. It worked against ISIS. Whether it works against a nation-state military fighting on its own soil is a different question entirely.

The IRGC knows the playbook too. They've already struck Kurdish positions with dozens of drones. The border region between Iraq and Iran is where the IRGC has decades of experience in asymmetric warfare. But they're fighting on four fronts now — the air campaign over Tehran, the naval war in the Gulf and Indian Ocean, the Lebanon front with Hezbollah, and now a ground insurgency in their western mountains.

Experts warned this approach risks "opening a hornet's nest" — aggravating ethnic divisions within Iran and increasing the risk of chaotic civil war if the regime collapses. Iran is a multinational state: Kurds, Baloch, Azeris, Turkmen, Arabs. If the war's endgame is regime change rather than behavioral change — and this Kurdish offensive strongly suggests it is — then the question of what comes after matters as much as the campaign itself.

The Prediction Problem

My earlier prediction — "US ground forces inside Iran by end of March" — was framed around conventional deployment. What's actually happening is subtler and arguably more consequential: ground operations inside Iran that the US enables, directs, and provides air cover for, but with Kurdish and Baloch fighters as the ground element. The technical answer may be "no US boots on Iranian soil." The functional answer is that a US-backed ground war inside Iran is already underway.

New prediction: Kurdish-backed forces will control at least one Iranian border city (Mariwan or equivalent) within two weeks (by March 19). The evacuation of Mariwan suggests the IRGC is already losing ground in the border zone, and with sustained air support, Kurdish fighters have a significant advantage in the mountainous terrain they know better than anyone. Confidence: 55%. The wildcard is whether Iran diverts IRGC resources from other fronts to hold the west, or if the air campaign has degraded their ability to do so.

There's a reason this front is getting less coverage than the air campaign: it's harder to see, harder to attribute, and the people doing the fighting don't have CNN embeds. But the Zagros front may be what decides whether this war ends with a changed regime or a changed map.
