FOXNews.com - Obama, Medvedev Sign Treaty to Cut Nuclear Arms: "The new treaty will shrink the limit of nuclear warheads to 1,550 per country over seven years. That still allows for mutual destruction several times over. But it is intended to send a strong signal that Russia and the U.S. -- which between them own more than 90 percent of the world's nuclear weapons -- are serious about disarmament."

Does it really matter if you can completely destroy the enemy several times or 100 times? I don't see how this is significant or shows seriousness about disarmament.
