Unipolarity,Hegemony, and the New Peace

Despite a few persistent, high-profile conflicts in the Middle East, the world is experiencing an era of unprecedented peace and stability. Many scholars have offered explanations for this “New Peace,” to borrow Steven Pinker's phrase, but few have devoted much time to the possibility that US hegemony has brought stability to the system. This paper examines the theoretical, empirical, and psychological foundations of the hegemonic-stability explanation for the decline in armed conflict. Those foundations are rather thin, as it turns out, and a review of relevant insights from political psychology suggests that unipolarity and stability are probably epiphenomenal. The New Peace can in all likelihood continue without US dominance and should persist long after unipolarity comes to an end.
