Why deterrence needs dialogue and détente

Since at least the time of the Greeks and the Romans it has been conventional wisdom that if you want peace prepare for war. Strong defences, military capabilities and demonstrating resolve can deter an enemy that might have thoughts of attack. American presidents from George Washington to Ronald Reagan (and even Donald Trump) have promoted the security benefits of “peace through strength”. Such logic will no doubt dominate security doctrines for the foreseeable future. But paradoxically, pure deterrence can be potentially destabilizing. Lack of communication with opponents can deepen distrust, create misperceptions and increase the risk of miscalculation. Therefore, at a time of high tensions in international relations, it is vital to retain some aspects of dialogue and détente if deterrence is to be credible and effective.
