With the killing of Osama bin Laden, President Obama closed one chapter of US history; unfortunately, the next is looming large.

As years of sanctions and careful diplomatic negotiations with Iran deteriorate into an increasingly fragile state of affairs, President Obama is left with few choices: attempt to restart what many consider failed negotiations or seriously consider a preventative strike.

Trita Parsi is the President of the National Iranian American Council and the author of the new book, A Single Roll of the Dice: Obama’s Diplomacy with Iran. He contends that diplomacy with Iran did not fail—it was abandoned. Real diplomacy has barely been tried, he argues, and it remains the only promising option for achieving America’s goals with regard to Iran.

Parsi will examine the Obama administration's early diplomatic gestures towards Iran and discuss the best ways to move toward more positive relations between the two discordant states.
