US ambassador to Israel Dan Shapiro sent a message to Iran on Wednesday at The Jerusalem Post
Diplomatic Conference, signalling the US's willingness to negotiate over the country's illicit nuclear program, but warning that its willingness would not extend indefinitely.
"Our message for Iran is that the window is open for diplomatic solution, but the window is not open indefinitely," he said. "Israel and US have a shared principle that no options are off the table. A nuclear Iran would embolden terror groups. The whole world must work to prevent a nuclear Iran."He added: "The US doesn't have a policy of containment but prevention."
