"I think it's wonderful that they want to do that, I'd be all for it," Trump said in an interview with news agency Reuters.

Trump declined to say if the United States would provide air cover to Kurdish forces.

Since the United States and Israel launched the war on Saturday, Iran has been striking Iranian Kurdish groups based in autonomous Iraqi Kurdistan whom Tehran accuses of serving Western and Israeli interests.

Several Iranian Kurdish groups back fighting for greater autonomy within Iran, angering the Islamic republic but also many opponents, including monarchists who insist on territorial integrity.

While Kurds have historically had less friction with the Iranian state than their brethren in Iraq, Turkey and Syria, Iranian Kurds form some of Iran's rare armed and organized opposition groups.

Experts say they could potentially help special forces infiltrate and destabilize Iran.
