Biden: US will talk to Iran, but could take pre-emptive action

US Vice President Joe Biden said the US is willing to talk with Iran, but will act to isolate and pressure Teheran if Iran continues its current course and does not abandon its nuclear ambitions and support for terrorism. In a sweeping speech to international leaders and security experts in Munich, Biden said the US will strive to act preventively to avoid having to choose between the risks of war and the dangers of inaction. But he held out the option that the United States could take pre-emptive action against Iran if necessary to stop crisis before they start.
