Phil Gurski has studied and countered terrorism for most of his adult life, first as a Canadian intelligence official, now as an esteemed commentator. In this book he condenses his knowledge and expresses his views, without pulling punches but in a constructive way, over two decades of War on Terror. Highly informed common sense for experts and laypeople alike.

Gurski is sketching a realistic path to end the war on terrorism. Amidst the abundance of literature on (counter)terrorism, Gurski is adding a rare but insightful piece to the debate: personal experiences of counterterrorism professionals. Reading Gurski means learning to defeat concrete threats and to accept the phenomenon of terrorism as part of civilisation.

In this small book, Phil Gurski provides a concise and incisive discussion of the big issues in the “war on terrorism”. Drawing on his long service as an analyst and a sound appreciation of scholarship, he provides a highly accessible, realistic, and informative survey of the strengths and weaknesses of the diverse responses to the threat by Western states.

An End to the War on Terrorism is worth reading as a jumping off point for stimulating a more in-depth plunge into the extant writings on terrorism/ counterterrorism of which there are hundreds to choose from today.
