The Washington Times called it "a dramatic foreign policy triumph." The liberal newspapers and TV networks were less enthusiastic, because they don't want to give credit to Bush for anything.
This bears much watching, because, after all, Putin is the former head of the KGB and Russia's experience with democracy is limited. But to reduce the cost and number of nuclear weapons while creating a missile shield against rogue nations would be the greatest foreign policy triumph since the end of the cold war. If Bush is stupid, we could use a lot more of it.
