Legion of Doom? China, Russia, Iran and North Korea

China, Russia, Iran and North Korea are deepening their security cooperation and, as a result, pose a growing challenge to the United States and its allies. These countries see the United States and its allies as a threat, have aggressive aims, and believe that the Western liberal order detracts from their stability and hinders their regional objectives. Although the depth of their relations is not as robust as that enjoyed by their Western rivals, their growing cooperation is a significant development in the global balance of power and has major implications for the West. US and allied planners must recognise that they cannot focus on only one adversary, such as China, and that a crisis in one part of the world is increasingly less likely to stay isolated, as each power may receive weapons, economic support and other assistance from others during a crisis.
