Washington: Preventing a "mad dash" by Iran to acquire nuclear weapons is America`s gravest foreign policy challenge and requires persistent, hard-nosed diplomacy, Senator John Kerry and a respected US statesman said on Wednesday.
Kerry, who chairs the Senate`s influential Foreign Relations Committee, led a hearing on US policy toward Iran and the options available to Washington as it reviews strategy over Tehran`s nuclear ambitions ahead of a new round of talks April 13 between the Islamic state and world powers.
With concern rising over a possible Israeli military strike on Iran`s atomic facilities, Kerry warned it was "certainly not realistic to expect that one high-level meeting is going to resolve all the differences or erase all of those decades of either misunderstandings or mistrust”.
"To have any prospect of success, we need an approach that gives diplomatic engagement space to breathe, without allowing Iran to play for time and drag us into a drawn-out process," the senior Democrat said.
"It won`t be easy to find a solution that might be acceptable to both sides, but also give the international community confidence that Iran neither has the capacity nor the desire to make a mad dash to nuclear weapons."
Former US undersecretary of state Tom Pickering told the hearing that foregoing diplomacy, negotiation and the use of sanctions in favour of a military strike on Iran could unleash a wave of terrorism against "soft American targets" worldwide.
"Iran or surrogates could attack businesses, non-governmental organisations, missionaries and virtually every American establishment in the region and beyond," said Pickering, a former ambassador to the United Nations as well as Russia, India and Israel.
He said hitting Iran`s nuclear facilities would set back bomb-making capacity by a number of years, but it "has a very high propensity in my view of driving Iran into the direction of openly declaring and deciding... to make a nuclear weapon seemingly to defend itself," against further attack.
That would only heighten tensions in an already convulsive region, he said.
Instead, the United States and its allies should concentrate on negotiation.
A good starting point, Pickering said, would be Iran`s earlier proposal that if they stop building up their uranium to 20 percent enrichment, the West would provide the fuel elements for the civilian Tehran Research Reactor. (AFP)
