Former US ambassador to the UN John Bolton said he didn't see "any signs whatsoever that President Obama would make the necessary decision" to strike the Iranian nuclear reactor.
Bolton claimed Israel seven days to strike before fuel rods are inserted into the reactor, after which any attack would result in radioactive fallout.
"I would be very surprised if there are any circumstances in which the Obama administration would use force against Iran's nuclear program," Bolton said.
"It has always been optimal that military force is used before the fuel rods are inserted," Bolton explained. "That's what Israel did in Osirak in 1991, and when they attacked the North Korean reactor built in Syria." Israel bombed the Osirak nuclear reactor in Iraq in 1991, and a Syrian reactor in 2007.
However Bolton didn't see any indication that an Israeli strike was going to happen. "Obviously if Israel were going to do something it wouldn't exactly be advertising it. But time is short."
Bolton said that if Iran were to gain nuclear capability, it would be a "much more dangerous world. That's why I think it's so critical. It won't stop with Iran. Saudi Arabia, Egypt, Turkey, perhaps other states as well."
