The Mission by Tim Weiner. An insider look into the CIA that any geopolitical enthusiast should read

I found this book on display in an airy library in the middle of Buenos Aires. Only a few years ago, I had read and loved The Jakarta Method by Vincent Bevins, an eye-opening deep dive into U.S. intelligence meddling in Southeast Asia and Latin America during the Cold War. So I knew this, a journalistic-style report covering the CIA from the late 1990s through 2023, would be right up my lane.

Still, this book surprised me from the very start.

For once, the level of detail and access far surpassed my expectations. Weiner names directors, station chiefs, analysts, field officers, policymakers. He goes deep into the CIA’s inner workings — its operations, its political pressures, who made decisions, who pointedly ignored them, and who paid the price.

You read about the post-9/11 war on terror, when the CIA added detention and so-called enhanced interrogation techniques to its portfolio. Much of this is described in uncomfortable detail. Even more jarring, though, is how improvised and directionless it all appears in hindsight: interrogations conducted by officers without professional training, no clear evidence that torture produced decisive intelligence, and the legality of these techniques constructed in real time.

The book moves into the Obama administration, showing the agency’s internal divisions and the growing reliance on drone warfare.

It spans broader global politics as well: how and why Putin’s ambitions were repeatedly underestimated in the early 2000s; the impact of WikiLeaks disclosures on CIA capabilities and reputation; the fragile diplomacy around Iran’s nuclear program leading up to the 2015 deal; and the shifting focus toward great-power competition with China.

The 2016 election is examined in detail. Weiner reconstructs how U.S. intelligence agencies gradually concluded that Russia was interfering to benefit Donald Trump, and how difficult it proved to communicate that assessment clearly and forcefully to the public in real time.

It's a dense but addictive read. At times I accepted that I would not remember every CIA director, deputy, or operative mentioned, but that was more than good enough for me.

But what this book does best is take a secretive, often misunderstood institution and, through countless stories and granular detail, humanize it. You see how much of global history turns on individual judgment, ego, fear, and miscalculation. It shows the CIA not as a formidable machine, but as an organization run by fallible people operating under extreme pressure.

And that is really the most terrifying part: how much human error exists where you wish there weren’t.
