Iran has made it to an all important meeting in Vienna, with representatives of world powers, where it will discuss plans for its current nuclear program.

Mohammad Javad Zarif, returned for the nuclear talks with the head of Iran's atomic energy agency Ali Akbar Salehi and Hossein Fereidoun -- Iranian President Hassan Rouhani's younger brother.

The parties in the talks include representatives from Russia, China, France, Germany and United Kingdom, and, as reported by the BBC, none of the groups expect to actually reach a deal by the time the deadline expires.

The convening P5+1 group -- a host of world powers that have joined diplomatic efforts to negotiate with Iran regarding its nuclear program -- wants the Islamic republic to scale back its nuclear activities in hopes that it will not build a nuclear weapon. Iran, in turn, wants international sanctions to be lifted in exchange, while maintaining that its nuclear program is in fact peaceful.

Iran's state news agency Irna remarked that the very fact that Salehi has joined the nuclear talks is a positive sign that Iran is serious in its desire to speed up the negotiations and achieve a deal.

Former CIA Director Michael Hayden expressed his lack of faith in any leverage the United States might have once had in nuclear negotiations with Iran. “I would actually fear that the Iranians have the upper hand right now,” Hayden told Fox News. “I actually fear we have painted ourselves into a corner where we believe that any deal is better than no deal at the present time.”

Zarif, speaking to reporters before his meeting with U.S. Secretary of State John Kerry, said, "I think the negotiations have reached a very delicate stage. We can make progress, but this will require political will -- and a lot of work needs to be done at this stage."
