Obama, Medvedev sign treaty to cut nuclear arms
Casting aside years of rancor, President Barack Obama and Russian President Dmitry Medvedev on Thursday signed the biggest nuclear arms pact in a generation, lacing the moment with new warnings of sanctions for an intransigent Iran.
The treaty, sealed after months of halting negotiation, is significant not just for what it does but for what it symbolizes: a fresh start for the United States and Russia, and evidence to a watching world that nuclear disarmament is more than a goal.
