Nearly four dozen nations signed a non-binding agreement Tuesday to secure vulnerable nuclear material by 2014, a goal President Obama said would make the world safer from a stockpile big enough to produce 120,000 nuclear bombs.http://www.usatoday.com/news/washington/2010-04-13-nuke-summit_N.htm
. . . Obama acknowledged there is no way to enforce the commitments made at the summit.
A non-binding agreement without an enforcement mechanism?
This does nothing to reverse the danger of "loose nukes" being turned into catastrophic weapons by terrorist groups or criminal gangs.
All it will take is one rogue or negligent country giving one cup of nuclear materials to one group of radical terrorists.
