Israeli Prime Minister Benjamin Netanyahu says sanctions are taking a bite out of Iran's economy but it is not enough.
"So far they haven't rolled back the Iranian program, or even stopped it by one iota," Netanyahu told CNN's Erin Burnett in an exclusive interview that will broadcast on Tuesday night.
"I can tell you the centrifuges are spinning. They were spinning before the talks began recently with Iran. They were spinning during the talks. They were spinning as we speak," Netanyahu said.
Netanyahu also expresses confidence that Israel knew what Iran was trying to do with its nuclear program. "We know," he said.
"This is not the case, the questions, people had about Saddam Hussein," Netanyahu said, referring to the faulty intelligence that was relied on ahead of the U.S. invasion of Iraq in 2003.
