In his famous 1990 essay in Foreign Affairs, Charles Krauthammer declared that the unipolar moment had arrived. He listed a few reasons to support his argument: there was no challenging power, nor was there likely any in the few decades, no power dispersion at the international level, and the former Soviet Union’s capacity was in decline. Thus, Krauthammer emphasised that at that time, there was no first-rate power in the world that could match the capacity of the US.
