The diplomatic gridlock between Iran and the West seemed immovable for decades. But on Sunday, diplomats made history when Iran and six world powers came together on an agreement over Iran's nuclear program.
The deal dials back Iran's ability to work toward a nuclear weapon and at the same time loosens the choke hold of international sanctions on Iran's economy.
The two sides now have six months to find out how historic the breakthrough really is. That's the duration of the preliminary agreement hammered out in Geneva, Switzerland, by Iran and the P5+1 - the five permanent members of the U.N. Security Council plus Germany.
"There are lots of things, regrettably, that we still have to work on. Our hope is that Iranian President Hassan Rouhani and Foreign Minister Javad Zarif want to build this different relationship, want to show in clear ways as we go forward that the program is peaceful," U.S. Secretary of State John Kerry told CNN's "State of the Union."

There were key meetings on Iran's nuclear program Saturday, but the clock is ticking for a deal to be reached during this round of negotiations.
Both sides have hinted that a deal in close, and foreign ministers from all the participating countries hastily flocked to Geneva, but as the hours passed, some ministers announced their intention to leave.

Momentum appears to be building for a breakthrough deal on Iran's nuclear program, with top diplomats flocking to the site of ongoing talks and one Western official saying Friday a deal could be reached "as soon as tonight."
U.S. Secretary of State John Kerry and British Foreign Secretary William Hague will both be in Geneva on Saturday. French Foreign Minister Laurent Fabius headed to the Swiss city on Friday night, according to an European Union diplomatic source, and Chinese Foreign Minister Wang Yi has left Beijing for Geneva, according to his ministry's website.FULL STORY

In a possible sign of a breakthrough, several top diplomats - including those from the United States, Russia, the European Union and Iran - met in or headed to Geneva on Friday for talks on Tehran's nuclear program.
U.S. State Department spokeswoman Jen Psaki said that Secretary of State John Kerry would depart for the Swiss city "later today with the goal of continuing to help narrow the differences and move closer to an agreement." The American diplomat is expected to land there around 7:45 a.m. Saturday (1:45 a.m. ET), according to a Western official.

Social work and community organizing may seem unlikely career experiences for a lead negotiator to draw on in high-stakes nuclear talks with Iran.
But in an interview before she headed to Geneva this week for the negotiations, Under Secretary of State for Political Affairs Wendy Sherman joked that while her caseload may be more global now, the work is similar.
“Understanding who the person is across the table from you, watching the group dynamics and knowing when to intervene, scoping out situations and seeing where the points of leverage are and how you can reach your objective, are a set of skills I was trained with earlier in my life and have used in any setting I have been in,” Sherman said. “You have to understand what you’ve come to achieve but be very cognizant of all of the other pieces. You need a 360-degree view.”

They may have been directed to a domestic audience, but some offensive remarks from Iran's supreme leader drew heated responses from senior officials in the Obama administration.
At issue were remarks by Ayatollah Ali Khamenei to a gathering of senior military officials in Tehran earlier this week in which he said Israeli officials "cannot be even called humans," and referred to Israeli Prime Minister Benjamin Netanyahu as "the rabid dog of the region."
"Well, obviously we disagree with it profoundly," Secretary of State John Kerry said in testimony before the Senate Foreign Relations Committee on Thursday.
"It's inflammatory and it's unnecessary, and I think at this moment, when we are trying to negotiate and figure out what can and can't be achieved, the last thing we need are names back and forth," Kerry said.

A majority of Americans support an interim deal with Iran that would ease some economic sanctions on that country in exchange for concessions on Iran's nuclear program, according to a new national poll.
A CNN/ORC International survey released Thursday indicates that 56% of the public would favor an international agreement that would impose major restrictions on Iran's nuclear program but not end it completely, with 39% opposed to such an agreement.
"Predictably, there is a partisan divide on that issue, with two-thirds of Democrats favoring a deal along those lines but only 45% of Republicans agreeing with that view," CNN Polling Director Keating Holland said.FULL STORY

Iran and world powers are resuming talks in Geneva amid high hopes that a diplomatic solution to Iran's nuclear program will finally be reached.
But while the P5+1 - the U.S., UK, France, Russia, China and Germany - and Iran appear to be closer than ever to striking a deal, there are still a lot of details to iron out.

A breakthrough deal on Iran's nuclear program could be on the horizon - even though Western allies are splintered on the terms.
World leaders will meet Wednesday in Geneva, Switzerland, to discuss a proposed deal that would loosen economic sanctions against Tehran in exchange for a suspension of part of its nuclear program.
The Geneva talks involve Iran and the five permanent members of the U.N. Security Council - the United States, Russia, China, Great Britain and France - as well as Germany in what is known as the P5+1 in diplomatic shorthand.
U.S. National Security Adviser Susan Rice said the plan would benefit the global community.

Chairman of the Joint Chiefs of Staff Gen. Martin Dempsey said Monday that if Israel were to strike Iran in an effort to damage the country's nuclear program, the United States would meet "some defined obligations" it has to the Middle East nation.
"I feel like we have a deep obligation to Israel," the military leader said. "That is why we are in constant contact and collaboration with them."
This fall, diplomats from the United States and other interested countries have met to deal with Iran's nuclear program and ways in which advancements could be halted.
