The United Nations Security Council has for 10 years said that a military nuclear program in Iran is unacceptable but may soon be forced to define what unacceptable means, former US secretary of state Henry Kissinger said at the Presidential Conference in Jerusalem on Tuesday.
Diplomacy should be given a chance, Kissinger said after receiving the Presidential Award of Distinction from President Shimon Peres. But "the question is at what point one concludes that negotiations have reached their limit."
Those two decisions should not be made unilaterally, he said. "It is something we should all do together."
