Barack Obama actually said...

"Barack Obama will lead a global effort to secure all nuclear weapons materials at vulnerable sites within four years."

"Barack Obama believes that we must urgently seek to reduce the risks from three potentially catastrophic threats: nuclear weapons, biological attacks, and cyber warfare."

"As president, he'll rebuild our alliances to take out terrorist networks."

"Today, we confront the possibility of terrorists bent on our destruction possessing a nuclear weapon or bomb-making materials."
