CNN News:伊朗核問(wèn)題達(dá)成協(xié)議 暫停部分鈾濃縮換減輕制裁

A deal after decades of diplomatic dead ends.

That's what we're going to jump in today on CNN STUDENT NEWS.

This particular deal involves Iran's controversial nuclear program.

The program has been a source of international concern for decades.

Iran says it only wants to use nuclear power for peaceful purposes.

Other countries believe Iran could use the program to make nuclear weapons.

For the past several weeks there have been negotiations between Iran and what's called the P5+1.

They are countries, the U.S., U.K., Russia, China, France and Germany.

There have been ten years of attempted negotiations over Iran's nuclear program.

This is the first time there has ever been an agreement.

And it's not a long lasting one: six months.

So, this is more of a preliminary deal.

Iran will make some changes to its nuclear program, and in return some of the economic sanctions, punishments that were used against Iran by the international community will ease up.

Some people are critical of this.

A Democratic U.S. senator says the deal favors Iran more than other countries.

A Republican Senator thinks it sets a bad precedent for other countries.

One analyst thinks that this deal can only be considered successful if it leads to a bigger agreement down the road, but he says reaching a deal was extraordinary.

In Geneva, a historic deal is struck.

For the first time in nearly a decade we have halted the progress of the Iranian nuclear program.

And key parts of the program will be rolled back.

Designed to block Iran from ever building a nuclear weapon.

These are substantial limitations, which will help prevent Iran from building a nuclear weapon.

Simply put, they cut off Iran's most likely path to a bomb.

After weeks of intense talks between Iran and six world powers in Geneva, crippling economic sanctions on Iran will be eased in all about $7 billion in relief.

In exchange, Iran agreed to halt enrichment of uranium above five percent, well below weapons grade and to dilute or convert its current stockpile of enriched uranium so it cannot be used for a weapon.

Iran also agreed to stop building or operating its Arak heavy water reactor, a second potential path to a bomb.

And Iran promised to be more open allowing intrusive daily monitoring of its nuclear program.

In answer to a question from CNN Iran's foreign minister Javad Zarif said the deal gave Iran what it has long sought, formal recognition of its freedom to a peaceful nuclear program.

Some Iranian officials are claiming that right has been recognized.

You say the program has been recognized.

The White House says there is no formal recognition of a right to enrich.

How did you square that circle?

The current ton of action as we call it in two distinct places has a very clear reference to the fact that Iranian enrichment program will continue and will be a part of any agreement, now and in the future.

Israeli's Prime Minister Benjamin Netanyahu, however, was sharply critical of the deal calling it "a historic mistake".

Iran is taking only cosmetic steps which it could reverse easily within a few weeks, and in return sanctions that took years to put in place are going to be eased.

Secretary Kerry offered these assurances to America's closest ally in the region.
