President Barack Obama: "....a step towards a "more hopeful world."
Iran's President Hassan Rouhani the deal proved that "constructive engagement works".
After many years of sanctions against the Iranian government and two full years of direct six party (even including Iran) negotiations, a nuclear deal has come to fruition (deal details). The deal is not an agreement between the United States and Iran. It was developed with full authorization of the United Nations and negotiated with the five members of the UN Security Council and the US.
(....the five permanent members of the United Nations Security Council—United States, Russia, China, France, United Kingdom—plus Germany and the European Union)
The deal awaits approval from both the Iranian government and religious leader (s) as well as approval from the US Congress.“Used with permission from the TPM websites, a service of TPM Media LLC.”
US-Iran Strike Historic Nuclear Deal (VIDEO)
UPDATE: July 14, 2015, 9:25 AM EDT
VIENNA (AP) — After long, fractious negotiations, world powers and Iran struck an historic deal Tuesday to curb Iran's nuclear program in exchange for billions of dollars in relief from international sanctions — an agreement aimed at averting the threat of a nuclear-armed Iran and another U.S. military intervention in the Middle East.
The accord marks a dramatic break from decades of animosity between the United States and Iran, countries that alternatively call each other the "leading state sponsor of terrorism" and the "the Great Satan."
"This deal offers an opportunity to move in a new direction," President Barack Obama said in early morning remarks from the White House that were carried live on Iranian state television. "We should seize it."
In Tehran, Iranian President Hassan Rouhani said "a new chapter" has begun in his nation's relations with the world. He maintained that Iran had never sought to build a bomb, an assertion the U.S. and its partners have long disputed.
Beyond the hopeful proclamations from the U.S., Iran and other parties to the talks, there is deep skepticism of the deal among U.S. lawmakers and Iranian hardliners. Obama's most pressing task will be holding off efforts by Congress to levy new sanctions on Congress or block his ability to suspend existing ones.
Sunni Arab rivals of Shiite Iran have also expressed concern over the deal. And Israel, which sees Iran as an existential threat, strongly opposes leaving the Islamic republic with nuclear infrastructure in place.
Watch Obama's full remarks on the deal, via C-SPAN:
Israeli Prime Minister Benjamin Netanyahu, who has furiously lobbied against a deal, called the agreement a "bad mistake of historic proportions."
Of course reaction from Israel's Netanyahu and the GOP as as expected. The first 2 minutes of this MSNBC video shows initial reaction to the "deal."
