President Obama and Russian President Dmitry Medvedev agreed Friday, to cut their nuclear arsenals by about a third -- marking the broadest arms deal in 20 years.
Both nations will still have enough weapons to destroy the other, but Obama said that's not the goal. He said the new treaty demonstrates a step toward a world without nuclear weapons.
"To put an end to Cold War thinking, we will reduce the role of nuclear weapons in our national security strategy and urge others to do the same," Obama said. "Make no mistake, as long as these weapons exist, the United States will maintain a safe, secure, and effective arsenal to deter any adversary."
The agreement requires the U.S and Russia reduce their arsenals of long-range nuclear weapons from 2,200 to 1,550 each. The new deal places no limits on missile defenses.
Unlike the 2002 Moscow Treaty, this new treaty includes checks and balances to ensure both countries meet their own obligations under the pact.
The treaty will have to be ratified by the U.S. Senate and the Russian Parliament, but Obama and Medvedev both plan to sign the agreement April 8 in Prague.
Analysts hope the treaty will move other nations to make nuclear reductions as well.
"I think that new treaty between Russia and the U.S. is very important for the world to keep control of the nuclear technologies especially military technologies," said Vladimir Ryzhkov, former deputy president of the Russian State Duma.
"And it will be very good and positive signal to everybody in the world, first of all, to Iran to stop the Iran nuclear program if they really planned to create a nuclear bomb," he said.
