He made these comments after speculation that the Gilad Shalit deal was a precursor to an attack:
"There is great convergence between us and the Americans regarding the diagnosis and the characterization of the situation in Iran," Barak said. "We know the Iranian leadership's goals, its determination and how it evades the world. We know what happened in Pakistan, we know what happened in North Korea and we see the immunity they have because of it. One should ask: Would Europe have intervened in Libya if Gadhafi had possessed nuclear weapons? Would the U.S. have toppled Saddam Hussein if he had nuclear weapons?"
Barak said that the Israeli public should not be concerned about the Iranian threat.
"I refuse to be intimidated, as if Iran could destroy Israel, " Barak said. "Israel is the most powerful country, from Tripoli to Tehran. There is no reason to be afraid of anything."
Israel must be concerned about rumors-- whether or not any attack is actually planned.
