Iran's main rebel group says it has the military might to overthrow Ayatollah Ruhollah Khomeini's government, but analysts dismiss the claim.

Hussein Mahdavi, a senior official of the Iraqi-based Mujahedeen Khalq, or People's Holy Warriors, would not say how long it might take to overthrow Iran's Islamic fundamentalist government."If you look at the divisions . . . inside the Khomeini regime, and compare it to the resistance ready at any time to overthrow the regime, you cannot seriously speak about needing years," he told The Associated Press.

Talk of overthrowing Khomeini is "sheer dreaming and sheer stupidity" said one Western military analyst, who spoke on condition of anonymity.

Even if the rebels did have an army ready to cross the border, analysts said, Iraqi President Saddam Hussein appears committed to peace negotiations and probably would not allow the insurgents to attack.
