Obama: 'United States has a moral responsibility to act'

Barack Obama has outlined his vision of a world free of nuclear weapons in a major speech in Europe.

The US president called for a global summit on nuclear security and the forging of new partnerships to prevent the spread of nuclear weapons.

He said he hoped to negotiate a new treaty to end the production of fissile materials for nuclear weapons.

North Korea's "provocative" rocket launch earlier in the day underscored the need for action, he said.

Although his nuclear goals might not be realised in his lifetime, he said he would strive to achieve them.

Mr Obama said that as long as Iran continued to pose a potential nuclear threat, the US would continue to work on a controversial missile defence shield, parts of which would be stationed in Poland and the Czech Republic.

He was speaking ahead of a meeting with EU leaders in the Czech capital, Prague, hours after North Korea launched a rocket despite international warnings.

Mr Obama condemned the launch: "Now is the time for a strong international response," he said.

"North Korea must know that the path to security and respect will never come through threats and illegal weapons."

Extermination of cities

Speaking to a 20,000-strong crowd in front of Prague's historic castle, Mr Obama said the US had a moral responsibility to act in ridding the world of nuclear weapons.

"The existence of thousands of nuclear weapons is the most dangerous legacy of the Cold War," he said.

"Today the Cold War has disappeared but thousands of those weapons have not."

He pledged to reduce the US nuclear stockpile, and urged others to do the same.

But as long as a nuclear threat existed, the US would retain its nuclear capability, although it would work to reduce its arsenal.

He said his administration would work to bring the Comprehensive Test Ban Treaty (CTBT) into force in order to achieve a global ban on nuclear testing.

The agreement would ban all nuclear explosions for any purpose, but cannot currently come into effect as nuclear powers such as the US and China have not ratified it, and India and Pakistan have not signed it.

Massive destruction

The most immediate and extreme threat to global security, the president said, was the possibility of terrorists possessing nuclear weapons.

"One terrorist with a nuclear weapon could unleash massive destruction," he said.

"Al-Qaeda has said it seeks a bomb. And that it would have no problem in using it. And we know that there is unsecured nuclear material across the globe."

Mr Obama announced a new effort to secure sensitive nuclear material within four years and break down the black market in the trade in illicit weapons.

He also said he would negotiate a new strategic arms reduction treaty with Russia by the end of this year.

The speech came days after he and Russian President Dmitry Medvedev - meeting on the sidelines of the G20 summit in London - agreed to reopen negotiations about reducing nuclear warheads.

They aim to produce a new arms control treaty to replace the Strategic Arms Reduction Treaty (Start) that expires at the end of the year.

Under Mr Obama's predecessor, George W Bush, tensions arose between the two sides over the US plan for a missile defence shield, parts of which would be stationed in Poland and the Czech Republic.

The new US administration is currently reviewing the plans, which are meant to counter nuclear attacks from countries like Iran and North Korea, but which Moscow sees as a threat.

Mr Obama said his administration would also seek to engage with Iran, presenting Tehran with a choice between getting access to peaceful nuclear energy, or risking isolation with its current nuclear strategy, which he said posed a clear threat.

"As long as the threat from Iran exists, we will go forward with a missile defence system," he said.

European pledges

His wide-ranging speech - which also touched on the need for a united approach to combat the global financial crisis and climate change - was rapturously received by the crowd.

Later Mr Obama met EU leaders for discussions on issues such as climate change and energy security.

He then flew to Turkey for the final stop of his European tour.

On Saturday, Mr Obama attended the Nato summit in Strasbourg, where he secured pledges from European nations to send more troops to Afghanistan to provide security for elections in August.

Mr Obama's first trip to Eastern Europe, 20 years after the end of the Cold War, was supposed to be the highlight of the Czech presidency of the EU.

But his official engagements there have been scaled down in the wake of Prime Minister Mirek Topolanek's resignation late last month, after losing a no-confidence motion.

Mr Topolanek - who has also described Mr Obama's stimulus plan as "the road to hell" - will remain in office until a new cabinet is appointed or fresh elections are held.
