the United States, together with our international

partners, has achieved something that decades

of animosity has not -- a comprehensive, long-term deal

with Iran that will prevent it from obtaining

a nuclear weapon.

This deal demonstrates that American diplomacy can bring

about real and meaningful change -- change that makes

our country, and the world, safer and more secure.

This deal is also in line with a tradition

of American leadership.

It's now more than 50 years since President Kennedy

stood before the American people and said,

"Let us never negotiate out of fear,

but let us never fear to negotiate."

He was speaking then about the need for discussions

between the United States and the Soviet Union,

which led to efforts to restrict the spread of nuclear weapons.

In those days, the risk was a catastrophic

nuclear war between two super powers.

In our time, the risk is that nuclear weapons will

spread to more and more countries, particularly

in the Middle East, the most volatile region in our world.

Today, because America negotiated from a position

of strength and principle, we have stopped

the spread of nuclear weapons in this region.

Because of this deal, the international community

will be able to verify that the Islamic Republic

of Iran will not develop a nuclear weapon.

This deal meets every single one of the bottom lines

that we established when we achieved a framework

earlier this spring.

Every pathway to a nuclear weapon is cut off.

And the inspection and transparency regime necessary

to verify that objective will be put in place.

Because of this deal, Iran will not produce the highly

enriched uranium and weapons-grade plutonium that

form the raw materials necessary for a nuclear bomb.

Because of this deal, Iran will remove two-thirds of its

installed centrifuges -- the machines necessary to produce

highly enriched uranium for a bomb -- and store

them under constant international supervision.

Iran will not use its advanced centrifuges

to produce enriched uranium for the next decade.

Iran will also get rid of 98 percent

of its stockpile of enriched uranium.

To put that in perspective, Iran currently has a stockpile

that could produce up to 10 nuclear weapons.

Because of this deal, that stockpile will be reduced

to a fraction of what would be required for a single weapon.

This stockpile limitation will last for 15 years.

Because of this deal, Iran will modify the core

of its reactor in Arak so that it will not produce

weapons-grade plutonium.

And it has agreed to ship the spent fuel from the reactor

out of the country for the lifetime of the reactor.

For at least the next 15 years, Iran will

not build any new heavy-water reactors.

Because of this deal, we will, for the first time,

be in a position to verify all of these commitments.

That means this deal is not built on trust;

it is built on verification.

Inspectors will have 24/7 access to Iran's

key nuclear facilities.

Inspectors will have access to Iran's entire nuclear

supply chain -- its uranium mines and mills,

its conversion facility, and its centrifuge manufacturing

and storage facilities.

This ensures that Iran will not be able to divert

materials from known facilities to covert ones.

Some of these transparency measures will be in place

for 25 years.

Because of this deal, inspectors will also

be able to access any suspicious location.

Put simply, the organization responsible for the inspections,

the IAEA, will have access where necessary, when necessary.

That arrangement is permanent.

And the IAEA has also reached an agreement with Iran to get

access that it needs to complete its investigation

into the possible military dimensions of Iran's

past nuclear research.

Finally, Iran is permanently prohibited from pursuing

a nuclear weapon under the Nuclear Non-Proliferation

Treaty, which provided the basis for the international

community's efforts to apply pressure on Iran.

As Iran takes steps to implement this deal,

it will receive relief from the sanctions that we put

in place because of Iran's nuclear program --

both America's own sanctions and sanctions imposed

by the United Nations Security Council.

This relief will be phased in.

Iran must complete key nuclear steps before

it begins to receive new sanctions relief.

And over the course of the next decade,

Iran must abide by the deal before additional sanctions

are lifted, including five years for restrictions related

to arms, and eight years for restrictions related

to ballistic missiles.

All of this will be memorialized and endorsed

in a new United Nations Security Council resolution.

And if Iran violates the deal, all of these sanctions

will snap back into place.

So there's a very clear incentive for Iran to follow

through, and there are very real consequences for a violation.

That's the deal.

It has the full backing of the international community.

Congress will now have an opportunity to review the

details, and my administration stands ready to provide

extensive briefings on how this will move forward.

As the American people and Congress review the deal,

it will be important to consider the alternative.

Consider what happens in a world without this deal.

Without this deal, there is no scenario where the world joins

us in sanctioning Iran until it completely dismantles

its nuclear program.

Nothing we know about the Iranian government suggests that

it would simply capitulate under that kind of pressure.

And the world would not support an effort to permanently

sanction Iran into submission.

We put sanctions in place to get a diplomatic resolution,

and that is what we have done.

Without this deal, there would be no agreed-upon limitations

for the Iranian nuclear program.

Iran could produce, operate and test more and more centrifuges.

Iran could fuel a reactor capable of producing

plutonium for a bomb.

And we would not have any of the inspections that allow

us to detect a covert nuclear weapons program.

In other words, no deal means no lasting constraints

on Iran's nuclear program.

Such a scenario would make it more likely that other countries

in the region would feel compelled to pursue their own

nuclear programs, threatening a nuclear arms

race in the most volatile region of the world.

It would also present the United States with fewer

and less effective options to prevent Iran

from obtaining a nuclear weapon.

I've been President and Commander-in-Chief for

over six years now.

Time and again, I have faced decisions

about whether or not to use military force.

It's the gravest decision that any President has to make.

Many times, in multiple countries,

I have decided to use force.

And I will never hesitate to do so when

it is in our national security interest.

I strongly believe that our national security interest now

depends upon preventing Iran from obtaining a nuclear weapon

-- which means that without a diplomatic resolution,

either I or a future U.S. President would face

a decision about whether or not to allow

Iran to obtain a nuclear weapon or whether to use

our military to stop it.

Put simply, no deal means a greater chance

of more war in the Middle East.

Moreover, we give nothing up by testing whether

or not this problem can be solved peacefully.

If, in a worst-case scenario, Iran violates the deal,

the same options that are available to me today will

be available to any U.S. President in the future.

And I have no doubt that 10 or 15 years from now,

the person who holds this office will be in a far

stronger position with Iran further away from a weapon

and with the inspections and transparency that

allow us to monitor the Iranian program.

For this reason, I believe it would be irresponsible

to walk away from this deal.

But on such a tough issue, it is important that

the American people and their representatives in Congress

get a full opportunity to review the deal.

After all, the details matter.

And we've had some of the finest nuclear scientists
