The chairman of the United States Joint Chiefs of Staff says the American military has a plan to attack Iran ,although he thinks a strike is probably a bad idea.
Admiral Mike Mullen, the highest-ranking US military officer, has often warned that a military strike on Iran would have serious and unpredictable ripple effects around the Middle East.
At the same time, he says the risk of Iran developing a nuclear weapon is unacceptable.
Mullen would not say which risk he thinks is worse. But he tells NBC television's "Meet The Press" that a military strike remains an option if need be.
And he says that, should it come to that, the military has a plan at hand. He didn't elaborate.
