But Bush told reporters at the start of a Group of Eight (G8) summit in Germany that "Russia is not going to attack Europe," and is "not something to be hyperventilating about."
Bush said he hopes to ease Russian concerns over U.S. missile-defense plans when he meets Putin today. The two leaders are expected to meet on the sidelines of the summit in Heiligendamm after 3 p.m. local time.
Before arriving in Germany, Bush said Russia had nothing to fear from the planned missile-defense system. But he also said democratic reforms had been "derailed" in Russia under Putin.
