Sources within the groups say that if Peshmerga fighters – security forces in the Kurdistan region – cross the border from northern Iraq into Iran, these networks and their supporters would join the fighters in securing the Kurdish region.
Some even believe that this could inspire an uprising by non-Kurdish Iranians.

“If the Peshmerga secure the Kurdish region, thousands of non-Kurdish Iranians will join them to finally free Iran,” one resident in Tehran said.
The Iraqi Kurds have been put in a difficult position. The US is a critical partner for the Kurdish authorities in Iraq, providing political as well as military support in terms of training, equipment and funding to the Iraqi Kurdish peshmerga forces.

But the Iraqi Kurdish authorities also have cordial diplomatic and commercial relations with Iran. Indeed, Kurdish officials, including President Nechirvan Barzani, say they will not allow their territory to be used to launch an attack on their neighbour.

Tehran said that it will not tolerate any incursion from Iraqi Kurdistan, and will target the Kurdistan Regional Government (KRG) if this happens.
