The Revisionist History of how the Iranian Nuclear Deal came about is already being written in America

The Iranian Nuclear Deal came about after :-

War Plans in Syria Were Forced Into Being Dropped

There was a massive public and Congressional outcry against bombing Syria in support of  Islamic Extremist terrorists funded by Saudi Arabia and Qatar
Thousands of phone calls were made by ordinary members of the public to members of Congress, demanding that the plans to bomb Syria be dropped.
The public was overwhelmingly against America starting another war in Syria - at least two thirds were against and possibly as high as 90%.
The British Parliament voted against military action in Syria
The Russians initiated a diplomatic deal to resolve the chemical weapons issue

These events forced Obama to drop his war plans in Syria which started with, but were definitely not limited to, a series of cruise missile strikes.
He could not get a vote approved in Congress and was extremely isolated.

The planned bombing of Syria had nothing whatsoever to do with the chemical weapons attack in Damascus on August 21st.

Iran elected a less bellicose President 

After the American Syrian war plans collapsed, the new Iranian President started a diplomatic initiative to try and resolve the on-going dispute and sanctions with America, regarding Iran's nuclear activities.

Despite initial reluctance, America eventually accepted Iran's new dovish approaches and sat down to talks with the Iranians.

Iran has been developing a civil nuclear program, since the 1950's.
It's oil production is declining because of a lack of investment.
It does not have enough oil refinery capacity to meet it's domestic demands.

Appendices, References and Background

Iran wants to develop both it's oil and gas production, but sanctions have played a large part in preventing this.
In July 2013, Iran signed a deal with Iraq and Syria to build a major gas pipeline (see above link).

Iran is getting around of the worst of the U.S. oil sanctions by selling oil to China and India.
China and India are getting cheaper oil, while America, Europe and other oil consumers are paying more.

Iran has been using up the uranium it has so far enriched, in it's domestic nuclear program.
Ehud Barak admitted that Iran has recently used 30% of it's semi enriched uranium for civilian purposes.

Ex-Mossad Chief: ‘US-Iran nuclear deal is good for Israel’

In November 2011, Halvey was quoted saying: “The US-Iran war could effect not only Israel, but the entire region for 100 years”. He also added that the “Jewish extremism in Israel poses a bigger risk than Ahmadinejad“.

There is zero evidence that Iran is developing a nuclear weapons capability.
Even if Iran did develop a nuclear weapon, Israel already has 80+ nuclear weapons and has the materials to quickly build 120 more.
The mullahs in Tehran may be mad, but they are not suicidal.
If Iran did ever launch a nuclear weapon against anyone, Tehran and much of Iran would be annihilated by a swift and massive Israeli and Western response.

If Iran ever did develop a nuclear weapon, it would be a deterrent, not a first strike weapon.
It would be a deterrent against Israeli and American aggression.

N.B. Israel has issued repeated numerous warnings that Iran is within 6 months or a year of developing a nuclear weapon for past 20 years.
So where is it? Even Israel states that Iran does not have them.

The real reason for so much tension with Iran, is that Israel wants to remain the only nuclear weapon power in the Middle East.
Although Israel's ally in the region Saudi Arabia, is now attempting to start it's own nuclear program with America's help.

Saudi Arabia and Israel want to remain the largest regional powers in the Middle East.
Since America's invasion of Iraq and the removal of Saddam Hussein as a counter weight, Iran has become a much stronger regional power.

Iran is the leader of the Shia Muslims in the Middle East.
There is an on-going sectarian war going on between Shia's and Sunni's (similar to the European wars between Catholics and Protestants from the 1500's).
Saudi Arabia is the leading power for the Sunni's, with it's extremist Wahhabi sect.

The conflicts between Saudi Arabia and Iran are also about oil and gas.
There is a global surplus of carbon energy reserves at current prices.
There is a shortage in distribution and refinery infrastructure.

There is competition between Saudi Arabia and Iran to supply the major markets of Europe, China and Asia.
(There is competition with Russia for energy supplies as well.)

Bibi Netanyahu & Ehud Barak tried to hijack a war with Iran in 2010. IDF & Mossad chiefs disagreed with them

There were several articles in November 2012 about Bibi Natanyahu and Ehud Barak trying to start a war with Iran in 2010.
Both the Israeli Defense Chief and Mossad chief disagreed with them and prevented it.
