A public diplomacy campaign by the Obama administration to convince world opinion that Iran was reneging on the Lausanne framework agreement in April has seriously misrepresented the actual diplomacy of the Iran nuclear talks.

As this week’s final nuclear talks got underway, there was one uninvited guest: Maryam Imanieh, the wife of Foreign Minister Mohammad Javad Zarif. She arrived at Vienna’s Palais Saxe-Coburg Hotel with Hossein Fereydoon, President Hassan Rouhani’s brother, adding a new twist to the final days of negotiations.

In his weekly address on Saturday, US President Barack Obama began his campaign to assure Americans and sway skeptics that the framework for a nuclear pact with Iran was a "good deal." A day after Obama called top lawmakers to urge support for the agreement, he pressed his case that Iran would not be able to build nuclear bombs.

And so it came, after years of protracted negotiations, extended deadlines and a diplomatic dance of unprecedented proportions – a deal that could signal a new era for Iran’s relations with the world. (...) Beyond the technical details of the agreement lies a triumph of diplomacy and the potential, if not for a realignment of US interests in the Middle East, then certainly a significant adjustment which has concerned its traditional allies in the region.

As the March 31st deadline to reach a political framework agreement between the P5+1 (United States, United Kingdom, France, China, Russia, and Germany) and Iran fast approaches, Congress is considering a number of initiatives dealing with Iran’s nuclear program. Whether or not there is an agreement with Iran, the issue is bound to be a significant focal point in U.S.-Iran relations for the foreseeable future.

While American negotiators maintained tight secrecy at the nuclear talks here, President Hassan Rouhani of Iran took to Twitter late Thursday to describe a letter he sent to President Obama and other world leaders justifying Iran’s positions.
