Biden to Iran: Time for diplomacy over nukes not unlimited

The window of opportunity for diplomacy over Iran's nuclear program "will not be opened indefinitely," US Vice President Joe Biden warned in an interview with the German daily Süddeutsche Zeitung on Friday.
The vice president urged Terhan to hold diplomatic talks and even take part in direct negotiations with the US, saying it is the "time and place" for successful diplomacy.
Biden told the German daily that Iran developing a nuclear bomb is a "threat to the national security of the United States," and assured that the US "will stop Iran from getting a nuclear weapon."
