Undersecretary of War for Policy Elbridge Colby outlined his vision for a “NATO 3.0″ to replace “NATO 2.0” in response to changing world dynamics.

Speaking at the NATO Defense Ministerial, Colby announced that the “unipolar moment” after the fall of the Soviet Union was now over, and that the United States and its allies must now prepare for a world in which the use of hard military power on a large scale by rivals is increasingly likely. He told the other NATO ministers that the U.S. had to prioritize the defense of the Western Hemisphere, and that the alliance must be ready for a potential simultaneous attack on multiple fronts.
