The international community and the United States have "no sense of urgency" when it comes to Iran's nuclear ambitions, Israeli Prime Minister Benjamin Netanyahu said Sunday.

In an interview with CBS News, Netanyahu suggested the various conflicts in the Middle East have diverted the West's attention and have allowed Iran to move forward with pursuing a nuclear bomb.

"I have a sense that there's no sense of urgency . . . on Iran," Netanyahu said on CBS's "Face the Nation." "And yet Iran is the most important, the most urgent matter of all . . . because all the problems that we have, however important, will be dwarfed by this messianic, apocalyptic, extreme regime that would have atomic bombs. It would make a terrible, catastrophic change for the world and for the United States."

Netanyahu also criticized new Iranian President Hasan Rowhani, whom the U.S. has expressed optimism about as a more moderate alternative to former President Mahmoud Ahmadinejad.

"He's criticizing his predecessor for being a wolf in wolf's clothing," Netanyahu said of Rowhani. "His strategy is be a wolf in sheep's clothing, smile and build a bomb."
