Tim Weiner, "The Mission: The CIA in the 21st Century" (Mariner Books, 2025) New Books in National Security

In 2007, Tim Weiner published the book Legacy of Ashes. It was a history of the CIA from its founding to the early 2000s. As a university student in Italy, I bought the book as soon as it came out. The second non-fiction book I ever bought in English. The book was riveting. It kickstarted my interest in the CIA and covert operations. Now, Tim Weiner has published a sequel to Legacy of Ashes. His new book is called The Mission: the CIA in the 21st Century (Mariner Books, 2025). It is a gripping and revelatory history of the from the late 1990s to the present. It ranges from 9/11 through the wars in Afghanistan and Iraq to today's battles with Russia and China–and with the President of the United States.  At the turn of the century, the Central Intelligence Agency was in crisis. The end of the Cold War had robbed the agency of its mission. More than thirty overseas stations and bases had been shuttered, and scores that remained had been severely cut back. Many countries where surveillance was once deemed crucial went uncovered. Essential intelligence wasn't being collected. At the dawn of the information age, the CIA's officers and analysts worked with outmoded technology, struggling to distinguish the clear signals of significant facts from the cacophony of background noise.  Then came September 11th, 2001. After the attacks, the CIA transformed itself into a lethal paramilitary force, running secret prisons and brutal interrogations, mounting deadly drone attacks, and all but abandoning its core missions of espionage and counterespionage. The consequences were grave: the deaths of scores of its recruited foreign agents, the theft of its personnel files by Chinese spies, the penetration of its computer networks by Russian intelligence and American hackers, and the tragedies of Afghanistan and Iraq. A new generation of spies now must fight the hardest targets–Moscow, Beijing, Tehran–while confronting a president who has attacked the CIA as a subversive force.  The book reveals how the agency fought to rebuild the espionage powers it lost during the war on terror–and finally succeeded in penetrating the Kremlin. The key message of the book is that the CIA must reclaim its original mission: know thy enemies. This is made even more difficult by the attacks on the intelligence community deployed by the second Trump presidency, from unqualified senior officials to loyalty tests. The fate of the free world hangs in the balance. The Mission includes exclusive on-the-record interviews with six former CIA directors, the top spymaster, thirteen station chiefs, and scores of top operations officers who served undercover for decades and have never spoken to a journalist before.
