Israel's defense minister has ruled out an attack on Iran - "for the moment."

"We have no intention, at the moment, of taking action, but the state of Israel is far from being paralyzed by fear," Defense Minister Ehud Barak told Israel Radio Thursday.

"It must act calmly and quietly - we don't need big wars," he said.

Barak said the Jewish state will keep its options open, including a military strike.
    
The United Nations nuclear watchdog agency, the International Atomic Energy Agency, recently reported Tehran is still developing nuclear technology, including designing a nuclear warhead.
    
Meanwhile, Barak said that Israeli opinion on the subject hasn't changed, stating that "a nuclear Iran is unacceptable" and Israel "is determined to stop that."
