It is likely that United States Secretary of State John Kerry is aware of the influence that he carries with him in regard to the ongoing Iranian nuclear talks in the Austrian capital city of Vienna, as Western nations desperately attempt to finalize an agreement prior to the November 24 deadline on Monday. However, if anyone knows why Kerry's arrival time in Vienna, originally scheduled for late Thursday, has been thrown up in the air, with sources unsure of whether he will arrive on Thursday or Friday, then the information has not been shared.
The Vienna negotiation process for a long-term arrangement regarding Iran's nuclear developments first began after an interim accord was struck with Iran in late 2013. Prior to the accord, 12 years of uneasy build-up raised the anxiety levels of national powers opposed to the development of any kind of nuclear weapon in the Middle Eastern country.
Iran's current situation is far from nuclear free, and the nation is actually looking to drastically expand its uranium sector in preparation for future nuclear reactors. Of course, Western representatives in Vienna are opposed to such a projection, and reports suggest that they are demanding that Iran reduce its nuclear infrastructure by half. However, Iran's President Hassan Rouhani does not appear to be overly affected by the considerable weight that is leaning against him, as he has made it clear that an amenable agreement will only be secured if the "other side shows the political will" and "doesn't make excessive demands".
Kerry arrived in Paris on Thursday morning, with the foreign ministers from Saudi Arabia and France awaiting his presence at a meeting. Awaiting Kerry in Vienna are the two remaining key issues: the future of Iran's nuclear infrastructure and the speed at which sanctions on Iran would be removed if a deal is agreed upon. According to British Foreign Minister Philip Hammond, a satisfactory conclusion will not be reached by the deadline, but the world will need to wait until Monday for the outcome.
