Part 1: Nuclear Program

Iran is a country led by a great president Mahmoud Ahmadinejad.Iran is islamic state in the middle east region. When the other middle eastern countries are Trying to shut the eye of a series of events Carried out by Israel and other Zionist, iran is a country That dared to oppose them. Why Iran can do this? 
Lets check this out from multiple sources ^ _ ^.
there has been much speculation on the cause of the attack iran, on the one hand there is the support of the attack, and on the other handsome are against such attacks. From some sources say that the origin of the attacks committed by Israel is because Iran began developing nuclear weapons.
Most of the "world"  know that nuclear development is prohibited unless conducted by the U.S. and Israel. Maybe some already know that they are the holder of the world today.

Iran’s nuclear program is one of the most polarizing issues in one of the world’s most volatile regions. While American and European officials believe Tehran is planning to build nuclear weapons, Iran’s leadership says that its goal in developing a nuclear program is to generate electricity without dipping into the oil supply it prefers to sell abroad, and to provide fuel for medical reactors.
Iran and the West have been at odds over its nuclear program for years. But the dispute has picked up steam since November 2011, with new findings by international inspectors, tougher sanctions by the United States and Europe, threats by Iran to shut the Strait of Hormuz to oil shipments and Israel signaled increasing readiness to attack Iran’s nuclear facilities.
Fears of an attack on Iran have driven up oil prices and represent a threat to  the already fragile state of a global economy still reeling from a sovereign debt crisis in Europe. At the same time, the Iranians have acutely felt the squeeze from a round of  sanctions aimed at getting Iran to freeze  its uranium enrichment program.
In March 2012, the global powers dealing with the program announced that they had accepted an Iranian offer to resume negotiations that broke off in stalemate more than a year before. Talks were set to begin in Turkey in mid-April, with both sides jostling for advantage in the days running up to the negotiations.
American and European diplomats said that one demand from the Obama administration and its allies would be a halt in the production of uranium fuel that is considered just a few steps from bomb grade, and a stop to the shipment of existing stockpiles of that fuel out of the country.


A Nuclear ‘Trigger’
Starting in early 2008, the United Nations’ International Atomic Energy Agency repeatedly accused Iran of dragging its feet in addressing “possible military dimensions” of its nuclear program. Tehran has declared that all of the evidence gathered by the agency — mostly from the intelligence agencies of member countries, and some from its own inspectors — are fabrications.
An I.A.E.A. report issued in February 2011 listed seven outstanding questions about work Iran apparently conducted on warhead design. The documents in the hands of the agency raise questions about work on how to turn uranium into bomb fuel, how to cast conventional explosives in a shape that can trigger a nuclear blast, how to make detonators, generate neutrons to spur a chain reaction, measure detonation waves and make nose-cones for missiles.
The May report gave new details for all seven of the categories of allegations. The disclosure about the atomic trigger centered on a rare material — uranium deuteride, a form of the element made with deuterium, or heavy hydrogen. Nuclear experts say China and Pakistan appear to have used the material as a kind of atomic sparkplug.
The report said it had asked Iran about evidence of “experiments involving the explosive compression of uranium deuteride to produce a short burst of neutrons” — the speeding particles that split atoms in two in a surge of nuclear energy. In a bomb, an initial burst of neutrons is needed to help initiate a rapid chain reaction.
Harold M. Agnew, a former director of the Los Alamos weapons laboratory, said the compression of uranium deuteride suggested work on an atomic trigger.
The agency’s disclosure about Iran’s alleged use of uranium deuteride also suggests another possible connection between Tehran’s program and Abdul Qadeer Khan, the rogue Pakistani engineer who sold nuclear information.
A famous photograph of Dr. Khan, whom Pakistan has released from house arrest in Islamabad, shows him in front of the schematic diagram of an atom bomb on a blackboard. A pointer to the bomb’s center is labeled uranium deuteride.
The May report also gave fresh charges on the design of missile warheads. Documentary evidence, it said, suggested that Iran had conducted “studies involving the removal of the conventional high explosive payload from the warhead of the Shahab-3 missile and replace it with a spherical nuclear payload.”
The Shahab-3 is one of Iran’s deadliest weapons, standing 56 feet tall. In parades, Iran has draped them with banners reading, “Wipe Israel off the map.”

Iran’s Nuclear History
Iran’s first nuclear program began in the 1960s under the shah. It made little progress, and was abandoned after the 1979 revolution, which brought to power the hard-line Islamic regime. In the mid-1990s, a new effort began, raising suspicions in Washington and elsewhere. Iran insisted that it was living up to its obligations under the Non-Proliferation Treaty, but in 2002, an exile group obtained documents revealing a clandestine program. Faced with the likelihood of international sanctions, the government of Mohammad Khatami agreed in 2003 to suspend work on uranium enrichment and allow a stepped-up level of inspections by the International Atomic Energy Agency while continuing negotiations with Britain, France and Germany.
In August 2005, Mr. Khatami, a relative moderate, was succeeded as president by Mr. Ahmadinejad, a hard-line conservative. The following January, Iran announced that it would resume enrichment work, leading the three European nations to break off their long-running talks. Under the Non-Proliferation Treaty, Iran has the right to enrich uranium, but the atomic energy association called for the program to be halted until questions about the earlier, secret program were resolved.
