Realism and European cooperation
The previous chapter investigated a puzzle for those realist research traditions that predict a balanced international system, namely the persistence of American dominance. A second anomaly with which realists struggle is the considerable European cooperation, and even integration, since the end of the Cold War. European cooperation during the Cold War could more easily be attributed to an external Soviet threat. It is much harder for realists to make a convincing argument for continuing cooperation after that threat disappeared.
