A Kurdish invasion of western Iran

Thursday 5 March 2026

The widening war between the United States, Israel and Iran has opened discussion of a new and potentially volatile front in the conflict: an uprising or armed incursion by Kurdish groups in western Iran. Reports indicate that Kurdish opposition factions operating from bases in Iraqi Kurdistan have been discussing with the United States the possibility of attacks upon Iranian security forces in the Kurdish regions of western Iran, particularly in the provinces collectively known to Kurds as Rojhelat, or Eastern Kurdistan. 

Such proposals sit at the intersection of long-standing Kurdish insurgencies, American strategic calculations in the Middle East, and the immediate military objectives of the US–Israeli campaign against Iran. Yet they also raise profound questions about whether a Kurdish intervention would constitute a guerrilla campaign, a conventional ground offensive, or something more ambiguous – and whether it could achieve any durable military or political results.

The strategic attraction of a Kurdish front

For both the United States and Israel, the attraction of encouraging Kurdish forces to attack Iranian security forces is straightforward. The current war has largely been fought through air strikes, missile exchanges and covert operations. Iran retains, however, a large and geographically dispersed internal security apparatus, including the Islamic Revolutionary Guard Corps (IRGC) and paramilitary Basij forces. Opening a Kurdish front could force Iran to divert troops away from other theatres, stretching her military capacity during a moment of strategic vulnerability. 

Reports suggest that the concept under discussion would involve Kurdish militias launching attacks on Iranian security installations and military units in western Iran, thereby tying down government forces and potentially encouraging wider unrest. Some proposals envision Kurdish attacks “tiring out” the regime’s forces and creating space for internal opposition to mobilise. 

From the American perspective this strategy resembles a classic indirect warfare approach. Rather than committing large US ground forces, Washington might seek to exploit internal fractures within Iran’s multiethnic society. Iran’s Kurdish population numbers several million people and has a long history of political unrest and insurgency. Kurdish groups have fought intermittent guerrilla campaigns against Tehran since the early years of the Islamic Republic. 

For Israel the logic is similar but perhaps even more immediate. A destabilised Iran divided by internal insurgencies would find it far more difficult to coordinate regional proxy forces such as Hezbollah or supply weapons to allied militias across the Middle East.

What the Kurds might hope to achieve

For Kurdish organisations themselves participation in such an operation could promise several long-term gains.

The principal Kurdish armed groups opposing Tehran – including the Kurdistan Free Life Party (PJAK), the Democratic Party of Iranian Kurdistan (PDKI), and the Komala movement – have historically sought some form of Kurdish self-rule or federal autonomy within Iran. 

If Iranian authority weakened in Kurdish areas, Kurdish leaders might attempt to establish autonomous administrations similar to those created in northern Syria during the Syrian civil war or in Iraqi Kurdistan after the collapse of Saddam Hussein’s control in 1991.

Some Kurdish factions may also view the present crisis as a rare historical opportunity. Iranian Kurdish insurgencies have often been suppressed through overwhelming force, assassinations of leaders and cross-border military operations. Yet if Iran’s armed forces were simultaneously engaged in a regional war and internal power struggles, Kurdish militants might perceive a window in which Tehran’s capacity for repression is temporarily weakened.

Nevertheless Kurdish participation would carry enormous risks. Kurdish political movements are fragmented, and not all factions support alignment with the United States or Israel. Some Iranian opposition groups have expressed concern that Kurdish separatism might fragment the Iranian state rather than democratise it.

Would this become a ground war?

The critical question is whether such Kurdish operations would amount to a genuine ground war inside Iran.

Most analysts believe that Kurdish forces currently lack the capacity to conduct a large-scale conventional invasion. The principal Kurdish militant organisation in Iran, PJAK, has historically specialised in guerrilla warfare rather than sustained territorial offensives. 

The Kurdish armed groups in question operate primarily from bases in Iraq’s autonomous Kurdistan Region and number at most a few thousand fighters combined. Their experience lies in mountain warfare, ambushes and small-unit attacks, not large mechanised assaults against a modern state military.

Consequently the most plausible scenario would involve a campaign of guerrilla raids, sabotage operations and targeted attacks on Iranian security installations. Kurdish units might infiltrate across mountainous border regions and conduct hit-and-run attacks designed to destabilise Iranian control rather than seize and hold territory.

Nevertheless even a limited guerrilla campaign could provoke a wider ground war. Iran has historically responded to Kurdish insurgency with massive retaliatory force, including artillery strikes, drone attacks and cross-border operations into Iraqi Kurdistan. Iranian missile strikes against Kurdish bases in Iraq have already occurred during previous crises. 

If Kurdish forces attempted to seize towns or establish “liberated zones”, the IRGC would likely deploy large ground formations to crush them.

Geography and the military challenges of western Iran

The terrain of western Iran presents both opportunities and obstacles for Kurdish insurgents.

The mountainous frontier between Iran and Iraq – particularly the Zagros mountain range – has long served as a sanctuary for Kurdish guerrilla groups. These rugged landscapes favour irregular warfare and can make large-scale mechanised operations difficult.

However, geography alone does not guarantee success. Iranian Kurdish regions are not isolated from the rest of the country. Iran maintains extensive road networks, military garrisons and surveillance capabilities throughout the area. Kurdish fighters would therefore face the challenge of operating within a heavily monitored environment.

Moreover Iran possesses a powerful internal security apparatus with decades of experience suppressing insurgencies. The IRGC has conducted repeated counterinsurgency campaigns against Kurdish rebels since the 1980s and has often succeeded in isolating insurgent groups from civilian populations.

Political obstacles and regional reactions

Perhaps the greatest challenges to any Kurdish offensive lie not on the battlefield but in regional politics.

Turkey, which has fought her own long war against Kurdish separatist groups linked to the PKK, is likely to view the arming of Iranian Kurdish militias with deep suspicion. Ankara has historically opposed any expansion of Kurdish armed movements near its borders.

Iraq also faces a delicate position. Kurdish militant groups launching attacks into Iran would likely do so from territory inside the Kurdistan Region of Iraq. This could expose Iraq to retaliation from Iran and complicate Baghdad’s already fragile political balance.

Finally Kurdish unity itself remains uncertain. Kurdish movements across Iran, Iraq, Syria and Turkey have different ideological orientations, rivalries and external alliances. Achieving coordinated military operations across these factions would be extremely difficult.

A risky strategy in a wider war

The prospect of Kurdish attacks inside Iran illustrates the increasingly complex character of the present Middle Eastern conflict. What began as an exchange of air strikes and missile attacks now threatens to spill into internal insurgencies and proxy wars across multiple borders.

For the United States and Israel, encouraging Kurdish action offers a way to weaken Iran without committing large ground forces. For Kurdish militants, it offers the possibility – however remote – of advancing long-standing aspirations for autonomy.

Yet the history of Kurdish insurgencies also offers a cautionary lesson. Kurdish uprisings in Iran have repeatedly begun with great optimism and ended in harsh repression. Iran’s state institutions remain powerful, and any Kurdish offensive could provoke devastating retaliation.

The result may therefore be neither a swift uprising nor a decisive campaign, but rather the opening of another slow and brutal front in a widening regional war.
