From the former director of GCHQ, learn the methodology used by the British intelligence agencies to reach judgements, establish the right level of confidence and act decisively. Intelligence officers discern the truth. They gather information - often contradictory or incomplete - and, with it, they build the most accurate possible image of the world. With the stakes at their absolute highest, they must then decide what to do.

In Spies, Lies, and Algorithms, Amy Zegart separates fact from fiction as she offers an engaging and enlightening account of the past, present, and future of American espionage as it faces a revolution driven by digital technology. Drawing on decades of research and hundreds of interviews with intelligence officials, Zegart provides a history of US espionage, gives an overview of intelligence basics and life inside America's intelligence agencies, and explores the vexed issues of traitors, covert action, and congressional oversight.

You might believe you’re thinking clearly in the moments that matter most. But in all likelihood, when the pressure is on, you won’t be thinking at all. And your subsequent actions will inevitably move you further from the results you ultimately seek—love, belonging, success, wealth, victory. According to Farnam Street founder Shane Parrish, we must get better at recognizing these opportunities for what they are, and deploying our cognitive ability in order to achieve the life we want.

We are approaching a critical threshold in the history of our species. Everything is about to change. Soon you will live surrounded by AIs. They will organize your life, operate your business, and run core government services. You will live in a world of DNA printers and quantum computers, engineered pathogens and autonomous weapons, robot assistants and abundant energy. None of us are prepared.

This urgent and eye-opening book makes the case that protecting humanity's future is the central challenge of our time. If all goes well, human history is just beginning. Our species could survive for billions of years - enough time to end disease, poverty, and injustice, and to flourish in ways unimaginable today. But this vast future is at risk. With the advent of nuclear weapons, humanity entered a new age, where we face existential catastrophes - those from which we could never come back.

We have never had so much information at our fingertips and yet most of us don’t know how the world really works. This book explains seven of the most fundamental realities governing our survival and prosperity. From energy and food production, through our material world and its globalization, to risks, our environment and its future, How the World Really Works offers a much-needed reality check—because before we can tackle problems effectively, we must understand the facts.

Today's "machine-learning" systems, trained by data, are so effective that we've invited them to see and hear for us - and to make decisions on our behalf. But alarm bells are ringing. Systems cull résumés until, years later, we discover that they have inherent gender biases. Algorithms decide bail and parole - and appear to assess black and white defendants differently. We can no longer assume that our mortgage application, or even our medical tests, will be seen by human eyes. And autonomous vehicles on our streets can injure or kill.

What passes for strategy in too many businesses, government agencies, and military operations is a toxic mix of wishful thinking and a jumble of incoherent policies. Richard P. Rumelt’s breakthrough concept is that leaders become effective strategists when they focus on challenges rather than goals, pinpointing the crux of their pivotal challenge—the aspect that is both surmountable and promises the greatest progress—and taking decisive, coherent action to overcome it.

The retired four-star general and and best-selling author of My Share of the Task shares a powerful new leadership model. Former General Stanley McChrystal held a key position for much of the War on Terror, as head of the Joint Special Operations Command. In Iraq, he found that despite the vastly superior resources, manpower, and training of the US Military, Al Qaeda had an advantage because of its structure as a loose network of small, independent cells. To defeat such an agile enemy, JSOC had to change its focus from efficiency to adaptability.

When we think about the future of war, the military and Washington and most everyone gets it backwards. We think in terms of buying single military systems, such as fighter jets or aircraft carriers. And when we think about modernizing those systems, we think about buying better versions of the same things. But what really matters is not the single system but "the battle network"—the collection of sensors and shooters that enables a military to find an enemy system, target it, and attack it.

Imagine a blackout lasting not days, but weeks or months. Tens of millions of people over several states are affected. For those without access to a generator, there is no running water, no sewage, no refrigeration or light. Food and medical supplies are dwindling. Devices we rely on have gone dark. Banks no longer function, looting is widespread, and law and order are being tested as never before.

Dubbed by Barron's as "The Shadow CIA", Stratfor, George Friedman's global intelligence company, has provided analysis to Fortune 500 companies, news outlets, and even the U.S. government. Now Friedman delivers the geopolitical story that the mainstream media has been unable to uncover, the startling truth behind America's foreign policy and war effort in Afghanistan, Iraq, and beyond.

CNN’s chief national security correspondent reveals the invisible fronts of 21st-century warfare and identifies the ongoing battles being waged - often without the public’s full knowledge - from disinformation campaigns to advanced satellite weaponry.

The Doomsday Machine is Ellsberg's hair-raising insider's account of the most dangerous arms buildup in the history of civilization, whose legacy - and renewal under the Obama administration - threatens the very survival of humanity. It is scarcely possible to estimate the true dangers of our present nuclear policies without penetrating the secret realities of the nuclear strategy of the late Eisenhower and early Kennedy years, when Ellsberg had high-level access to them.

Politicians and pundits on both sides of the aisle have accused Russia of interfering with our elections and our intelligence agencies. But the war Russia is waging against America is very different from anything you have heard in the press, as Russian-born US intelligence expert Rebekah Koffler reveals. In Putin’s Playbook, Koffler details how Vladimir Putin is orchestrating a wide-ranging, multifaceted campaign to retake his country’s role as a superpower and to defeat America in the process.

Written in an accessible and authoritative voice, The Button reveals the shocking tales and sobering facts of nuclear executive authority throughout the atomic age, delivering a powerful condemnation against ever leaving explosive power this devastating under any one person's thumb.

In Your Government Failed You, Clarke looks at why failures have continued and how America and the world can succeed against the terrorists. But Clarke goes beyond terrorism to examine the recurring U.S. government disasters. Despite the lessons of Vietnam, we've gotten involved in Iraq. Drawing on his 30 years in the White House, Pentagon, State Department, and Intelligence Community, Clarke discovers patterns in the failure and suggests ways to stop the cycle.

Warnings is the story of the future of national security, threatening technologies, the US economy, and possibly the fate of civilization. In Greek mythology Cassandra foresaw calamities, but was cursed by the gods to be ignored. Modern-day Cassandras clearly predicted the disasters of Katrina, Fukushima, the Great Recession, the rise of ISIS, and many more. Like the mythological Cassandra, they were ignored. There are others right now warning of impending disasters, but how do we know which warnings are likely to be right?

Author of the number one New York Times best seller Against All Enemies, former presidential advisor and counter-terrorism expert Richard A. Clarke sounds a timely and chilling warning about America's vulnerability in a terrifying new international conflict -cyber war! Every concerned American should listen to this startling and explosive book that offers an insider's view of White House situation room operations and carries the listener to the frontlines of our cyber defense. Cyber War exposes a virulent threat to our nation's security.

My Journey at the Nuclear Brink is a continuation of William J. Perry's efforts to keep the world safe from a nuclear catastrophe. It tells the story of his coming of age in the nuclear era, his role in trying to shape and contain it, and how his thinking has changed about the threat these weapons pose. In a remarkable career, Perry has dealt firsthand with the changing nuclear threat.

Red teaming. It is a practice as old as the Devil's Advocate, the 11th-century Vatican official charged with discrediting candidates for sainthood. Today, red teams - comprised primarily of fearless skeptics and those assuming the role of saboteurs who seek to better understand the interests, intentions, and capabilities of institutions or potential competitors - are used widely in both the public and private sector.

GCHQ is the largest and most secretive intelligence organisation in the UK, and has existed for 100 years - but we still know next to nothing about it. In this ground-breaking book - the first and most definitive history of the organisation ever published - intelligence expert Richard Aldrich traces GCHQ’s development from a wartime code-breaking operation based in the Bedfordshire countryside into one of the world leading espionage organisations.

CNN’s chief national security correspondent reveals the invisible fronts of 21st-century warfare and identifies the ongoing battles being waged - often without the public’s full knowledge - from disinformation campaigns to advanced satellite weaponry.

For the better part of the last half century, the United States has been the world's police, claiming to defend ideologies, allies, and our national security through brute force. But is military action always the most appropriate response? Drawing on his vast experience, retired four-star general Tony Zinni argues that we have a lot of work to do to make the process of going to war-or not-more clear-eyed and ultimately successful.

Packed with insider information based on interviews, declassified files, and forensic analysis of company reports, The Hacker and the State sets aside fantasies of cyber-annihilation to explore the real geopolitical competition of the digital age. Tracing the conflict of wills and interests among modern nations, Ben Buchanan reveals little-known details of how China, Russia, North Korea, Britain, and the United States hack one another in a relentless struggle for dominance.

The Internet today connects roughly 2.7 billion people around the world, and booming interest in the "Internet of things" could result in 75 billion devices connected to the web by 2020. The myth of cyberspace as a digital utopia has long been put to rest. Governments are increasingly developing smarter ways of asserting their national authority in cyberspace in an effort to control the flow, organization, and ownership of information.

The Perfect Weapon is the startling inside story of how the rise of cyberweapons transformed geopolitics like nothing since the invention of the atomic bomb. Cheap to acquire, easy to deny, and usable for a variety of malicious purposes, cyber is now the weapon of choice for democracies, dictators, and terrorists. Two presidents - Bush and Obama - drew first blood with Operation Olympic Games, which used malicious code to blow up Iran’s nuclear centrifuges, and yet America proved remarkably unprepared when its own weapons were stolen from its arsenal.

Since 9/11, why have we won smashing battlefield victories only to botch nearly everything that comes next? In the opening phases of war in Afghanistan, Iraq, and Libya, we mopped the floor with our enemies. But in short order, things went horribly wrong. We soon discovered we had no coherent plan to manage the "day after". The ensuing debacles had truly staggering consequences - many thousands of lives lost, trillions of dollars squandered, and the apparent discrediting of our foreign policy establishment.
