The US president called for the forging of new partnerships to prevent the spread of nuclear weapons, and a global summit on nuclear security, which will take place next month.
He spoke of putting an end to Cold War thinking, a process in which, he insisted, the US was morally obliged to play a leading role.
The next five-yearly review conference of the Nuclear Non-Proliferation Treaty is to be held in May.

Ahead of the summit, the Obama administration began a wide-ranging nuclear policy review, which was supposed to have been ready by now.
The BBC's Jonathan Marcus says all the signs are that the first draft of the document has been rejected as being too wedded to the status quo and not sufficiently "transformational" to use the language favoured by the Obama administration.
He says the review will be read closely to see what it might say about the potential circumstances in which nuclear weapons would be used, an issue Mr Obama is to discuss with Mr Gates.
The document will also set the tone for the next five-yearly review conference of the Nuclear Non-Proliferation Treaty, or NPT agreement, to be held in May.
Jonathan Marcus says Mr Obama will want to prevent the weakening NPT regime from unravelling, and to do so he needs to have powerful evidence that the US is taking its disarmament responsibilities seriously.
STRATEGIC NUCLEAR WARHEADS AROUND THE WORLD All numbers are estimates because exact numbers are top secret. Strategic nuclear warheads are designed to target cities, missile locations and military headquarters as part of a strategic plan. Israel Israeli authorities have never confirmed or denied the country has nuclear weapons. North Korea The highly secretive state claims it has nuclear weapons, but there is no information in the public domain that proves this. Iran The International Atomic Energy Agency reported in 2003 there had been covert nuclear activity to make fissile material and continues to monitor Tehran's nuclear programme. Syria US officials have claimed it is covertly seeking nuclear weapons.
