As the armies of the West begin a shift away from counterinsurgency (COIN) and the US Army, in particular, renews its focus on peer on peer warfare, the timing of the publication of Insurgencies and Counterinsurgencies by Jeremy Black could seem to have missed the COIN revolution. In the age of a resurgent Russia annexing the Crimea and threatening Baltic NATO members with a similar fate, is COIN still relevant or is it an idea to confine to a dusty shelf while the West learns how to confront Russian cross domain coercion and multi-domain battle? Despite the cognitive shift from COIN back to a paradigm of armor and mechanization, “wars amongst the people” - a phrase that popularized in Rupert Smith's The Utility of Force - are here to stay.
