Operating in the Gray Zone: Countering Iran's Asymmetric Way of War

Michael Eisenstadt

The targeted killing of IRGC Qods Force commander Qasem Soleimani marked the dramatic culmination of several months of U.S. tensions with Iran. It has raised the urgent question of how Tehran will respond, and stoked fears of a broader conflict. Since 1979, the Islamic Republic has distinguished itself as perhaps the foremost practitioner of “gray zone” activities, and for nearly four decades the United States has struggled to respond effectively to this asymmetric way of war. For this reason, it is more important than ever for Washington to understand Tehran’s strategy and devise its own gray zone strategy to counter it.

In this timely Policy Focus, military analyst Michael Eisenstadt details how the Islamic Republic operates in the gray zone between war and peace to manage escalation, leverages asymmetries to achieve disproportionate effects, and employs its hybrid force structure for maximum effect. The current U.S. approach, he explains, is based on overt action, blunt force, and emphatic messaging, all of which entail a heightened potential for escalation. But an alternative approach—one focused on unacknowledged activities, indirection, subtlety, and discreet messaging—could more effectively deter Iran while reducing the risk of further escalation and broader conflict.
