Twenty-five years after the attacks of September 11, 2001, former Canadian intelligence analyst Phil Gurski delivers a sober and deeply informed assessment of what the world misunderstood about terrorism, intelligence, and national security in the aftermath of 9/11. Drawing on decades inside Canada's intelligence community, 9/11 The Unfinished Battle examines how the Global War on Terror reshaped governments, intelligence agencies, geopolitics, and civil liberties―while failing to eliminate the threat it sought to destroy. Far from a retrospective history, this book is a forward-looking analysis of how terrorism, espionage, foreign interference, and transnational repression continue to evolve.

Gurski argues that the West's greatest mistake was assuming the threat landscape had fundamentally changed, when in reality many of the same ideological and geopolitical forces remain firmly in place. Combining intelligence insight with geopolitical analysis, 9/11 The Unfinished Battle offers a pragmatic blueprint for building long-term security without sacrificing democratic values while informing the public that the threat is omnipresent and our governments need to take the threat seriously.

"Phil Gurski delivers a clear, compelling, and deeply informed account of the global War on Terror, from its violent beginnings to the unstable world it has helped create today." -Martin Gallagher, PhD Ideal for readers of Malcolm Gladwell, Ben Rhodes, and contemporary geopolitical nonfiction, this is an essential examination of the unfinished legacy of 9/11―and what comes next.
