Obama Calls for World Without Nuclear Weapons – washingtonpost.com:
In a speech grimly punctuated by current events, President Obama Sunday called for a world without nuclear weapons shortly after North Korea defied global warnings to fire a long-range rocket.
Speaking in front of the Prague Castle just hours after the North Korean launch, Obama vowed to immediately seek U.S. ratification of a ban on nuclear testing, convene a summit in Washington to stop the spread of nuclear material within four years and create a nuclear fuel bank to allow peaceful development of nuclear power.
“I state clearly and with conviction America’s commitment to seek the peace and security of a world without nuclear weapons,” Obama said to a crowd of about 20,000 packed into the historic square in the Czech Republic’s capital city. “This goal will not be reached quickly — perhaps not in my lifetime. It will take patience and persistence. But now we, too, must ignore the voices who tell us that the world cannot change.”
