"It is time for Russia to be true to its word and to act to end this crisis."

"The United States, Europe and all other concerned countries must stand united in condemning this aggression, and seeking a peaceful resolution to this crisis."

--Sen. Barack Obama

"Whatever tensions and hostilities might have existed between Georgians and Ossetians, they in no way justify Moscow's path of violent aggression. Russian actions, in clear violation of international law, have no place in 21st century Europe."

-- Sen. John McCain
