There is space,time for diplomatic solution: US on Iran

8220;We8217;re reviewing the letter,8221; Carney said.

8220;We have certainly noted in the past that the Iranians needed to respond to that letter. So they have. But I don8217;t want to make any qualitative judgements about their response at this time.8221;

Carney said if Iran chooses a path of 8220;honouring its international obligations and working with the international community to remove the world8217;s concerns about its development of a nuclear weapons program8221;,then there is an opportunity for Iran to work its way out of the corner that its behaviour has led them into.
