    General H.R. McMaster, U.S. Army, ret., the former National Security Advisor and author of the bestselling classic Dereliction of Duty, comes a bold and provocative re-examination of the most critical foreign policy and national security challenges that face the United States, and an urgent call to compete to preserve America’s standing and security.Across multiple administrations since the end of the Cold War, American foreign policy has been misconceived, inconsistent, and poorly implemented. As a result, America and the free world have fallen behind rivals in power and influence. Meanwhile threats to security, freedom, and prosperity, such as nuclear proliferation and jihadist terrorism have grown. In BATTLEGROUNDS, H.R. McMaster describes efforts to reassess and fundamentally shift policies while he was National Security Advisor. And he provides a clear pathway forward to improve strategic competence and prevail in complex competitions against our adversaries.BATTLEGROUNDS is a groundbreaking reassessment of America’s place in the world, drawing from McMaster’s long engagement with these issues, including 34 years of service in the U.S. Army with multiple tours of duty in battlegrounds overseas and his 13 months as National Security Advisor in the Trump White House. It is also a powerful call for Americans and citizens of the free world to transcend the vitriol of partisan political discourse, better educate themselves about the most significant challenges to national and international security and work together to secure peace and prosperity for future generations.

    The tycoon had close ties to the U.S. government, and he soon asked Elizebeth to apply her language skills to an exciting new venture: code-breaking. There she met the man who would become her husband, groundbreaking cryptologist William Friedman. In The Woman Who Smashed Codes, Jason Fagone chronicles the life of Elizebeth Smith who played an integral role in our nation's history for forty years. After World War I, Smith used her talents to catch gangsters and smugglers during Prohibition, then accepted a covert mission to discover and expose Nazi spy rings that were spreading like wildfire across South America, advancing ever closer to the United States. As World War II raged, Elizebeth fought a highly classified battle of wits against Hitler's Reich, cracking multiple versions of the Enigma machine used by German spies. Meanwhile, inside an Army vault in Washington, William worked furiously to break Purple, the Japanese version of Enigma--and eventually succeeded, at a terrible cost to his personal life.Fagone unveils America's code-breaking history through the prism of Smith's life, bringing into focus the unforgettable events and colorful personalities that would help shape modern intelligence.

    counterterrorism operations and oversaw the use of those procedures—procedures that obtained vital and timely intelligence and helped safeguard the nation from future attacks. Puerto Rican–born Jose A. Rodriguez, Jr., served the United States for twenty-five years as an undercover officer before bringing his wealth of field knowledge to the CIA’s Counterterrorism Center; now, in this riveting account and fascinating life story, one of America’s top undercover operatives reveals how hard measures have derailed terrorist activity targeting the U.S., and saved countless American lives. Fully disclosed here for the first time are the undercover operations and tactics implemented during the George W. Bush presidency—which were approved by the highest levels of the U.S. government, certified as legal by the Department of Justice, and supported by bipartisan leadership of congressional intelligence oversight committees. But as the shock of 9/11 faded, the support that the intelligence community enjoyed and deserved gave way to shortsighted and potentially dangerous political correctness. One by one, the tools needed to successfully fight terrorism were banished, and the men and women who volunteered to carry out our nation’s orders in combating al-Qa'ida found themselves second-guessed, hamstrung, and investigated— including Rodriguez himself. In effect, the United States has chosen to willfully and unilaterally disarm itself in the war on terror. In Hard Measures, Rodriguez convincingly argues for the techniques used, and uncompromisingly details when these techniques were necessary, why they worked, and how, ultimately, they contributed to the capture of the world’s most-wanted terror operatives, including Usama bin Ladin. From law school student to CIA recruit to his role as America’s top spy, Rodriguez’s full story is one of utmost importance—a rare, insider’s look at an issue that demands attention. Above all, it’s a reasoned, imperative, and fully informed case for hard measures, and an explosive and gripping account of the real war on terror— where it’s been and where it’s headed. Terrorism has always been one of the toughest targets on which to collect intelligence. The secrets you want to steal frequently don’t reside in computer systems, which can be hacked, or safes, which can be broken into, but in the inner recesses of a handful of individuals’ minds. The cliché about intelligence work is that it is like working on a thousand-piece jigsaw puzzle but not having the box top to show you what the finished picture should look like. If only it were that easy. In fact, it is more like working on a million-piece puzzle with no box top, and having millions more random pieces that look like they might fit, but actually are from different puzzles altogether. It fell to us to make sense of the countless fragments of information and to take action on the chunks of the puzzle, which represented a real and growing threat to the United States and our allies.

    From Bob Woodward, legendary investigative reporter, Veil is the story of the covert wars that were waged by the CIA across Central America, Iran and Libya in a secretive atmosphere and became the centerpieces and eventual time bombs of American foreign policy in the 1980s.With unprecedented access to the government’s highest-level operators, Woodward recounts one of the most clandestine operations in our nation’s history.

    Yet as early as 1993, CIA director James Woolsey pointed out that although Western powers had slain a large dragon by defeating the Soviet Union, they now faced abewildering variety of poisonous snakes. In The Dragons and the Snakes, the eminent soldier-scholar David Kilcullen asks how, and what, opponents of the West have learned during the last quarter-century of conflict. Applying a combination of evolutionary theory and detailed field observation, heexplains what happened to the snakes--non-state threats including terrorists and guerrillas--and the dragons--state-based competitors such as Russia and China. He explores how enemies learn under conditions of conflict, and examines how Western dominance over a very particular, narrowly-definedform of warfare since the Cold War has created a fitness landscape that forces adversaries to adapt in ways that present serious new challenges to America and its allies. Within the world's contemporary conflict zones, state and non-state threats have increasingly come to resemble each other, withstates adopting non-state techniques and non-state actors now able to access lethal weapon systems once only available to governments. A counterintuitive look at a vastly more complex conflict environment, this book both reshapes our understanding of the West's adversaries and shows how we canrespond given the increasing limits on US power.

    Within the year, the treaty signed that day, known as the Peace Pact, had been ratified by nearly every state in the world. War, for the first time in history, had become illegal the world over. But the promise of that summer day was fleeting. Within a decade of its signing, each state that had gathered in Paris to renounce war was at war. And in the century that followed, the Peace Pact was dismissed as an act of folly and an unmistakable failure. This book argues that that understanding is inaccurate, and that the Peace Pact ushered in a sustained march toward peace that lasts to this day. The Internationalists tells the story of the Peace Pact by placing it in the long history of international law from the seventeenth century through the present, tracing this rich history through a fascinating and diverse array of lawyers, politicians and intellectuals—Hugo Grotius, Nishi Amane, Salmon Levinson, James Shotwell, Sumner Welles, Carl Schmitt, Hersch Lauterpacht, and Sayyid Qutb. It tells of a centuries-long struggle of ideas over the role of war in a just world order. It details the brutal world of conflict the Peace Pact helped extinguish, and the subsequent era where tariffs and sanctions take the place of tanks and gunships. The Internationalists examines with renewed appreciation an international system that has outlawed wars of aggression and brought unprecedented stability to the world map. Accessible and gripping, this book will change the way we view the history of the twentieth century—and how we must work together to protect the global order the internationalists fought to make possible.

    From the very beginning of its statehood in 1948, protecting the nation from harm has been the responsibility of its intelligence community and armed services, and there is one weapon in their vast arsenal that they have relied upon to thwart the most serious threats: Targeted assassinations have been used countless times, on enemies large and small, sometimes in response to attacks against the Israeli people and sometimes preemptively. In this page-turning, eye-opening book, journalist and military analyst Ronen Bergman offers a riveting inside account of the targeted killing programs—their successes, their failures, and the moral and political price exacted on the men and women who approved and carried out the missions.Bergman has gained the exceedingly rare cooperation of many current and former members of the Israeli government, including Prime Ministers Shimon Peres, Ehud Barak, Ariel Sharon, and Benjamin Netanyahu, as well as high-level figures in the country’s military and intelligence services: the IDF (Israel Defense Forces), the Mossad (the world’s most feared intelligence agency), Caesarea (a “Mossad within the Mossad” that carries out attacks on the highest-value targets), and the Shin Bet (an internal security service that implemented the largest targeted assassination campaign ever, in order to stop what had once appeared to be unstoppable: suicide terrorism).Including never-before-reported, behind-the-curtain accounts of key operations, and based on hundreds of on-the-record interviews and thousands of files to which Bergman has gotten exclusive access over his decades of reporting, Rise and Kill First brings us deep into the heart of Israel’s most secret activities. Bergman traces, from statehood to the present, the gripping events and thorny ethical questions underlying Israel’s targeted killing campaign, which has shaped the Israeli nation, the Middle East, and the entire world.

    Lawrence Wright's remarkable book is based on five years of research and hundreds of interviews that he conducted in Egypt, Saudi Arabia, Pakistan, Afghanistan, Sudan, England, France, Germany, Spain, and the United States.The Looming Tower achieves an unprecedented level of intimacy and insight by telling the story through the interweaving lives of four men: the two leaders of al-Qaeda, Osama bin Laden and Ayman al-Zawahiri; the FBI's counterterrorism chief, John O'Neill; and the former head of Saudi intelligence, Prince Turki al-Faisal.As these lives unfold, we see revealed: the crosscurrents of modern Islam that helped to radicalize Zawahiri and bin Laden . . . the birth of al-Qaeda and its unsteady development into an organization capable of the American embassy bombings in Kenya and Tanzania and the attack on the USS Cole . . . O'Neill's heroic efforts to track al-Qaeda before 9/11, and his tragic death in the World Trade towers . . . Prince Turki's transformation from bin Laden's ally to his enemy . . . the failures of the FBI, CIA, and NSA to share intelligence that might have prevented the 9/11 attacks.The Looming Tower broadens and deepens our knowledge of these signal events by taking us behind the scenes. Here is Sayyid Qutb, founder of the modern Islamist movement, lonely and despairing as he meets Western culture up close in 1940s America; the privileged childhoods of bin Laden and Zawahiri; family life in the al-Qaeda compounds of Sudan and Afghanistan; O'Neill's high-wire act in balancing his all-consuming career with his equally entangling personal life--he was living with three women, each of them unaware of the others' existence--and the nitty-gritty of turf battles among U.S. intelligence agencies.Brilliantly conceived and written, The Looming Tower draws all elements of the story into a galvanizing narrative that adds immeasurably to our understanding of how we arrived at September 11, 2001. The richness of its new information, and the depth of its perceptions, can help us deal more wisely and effectively with the continuing terrorist threat.

    It is a conflict that has never been acknowledged and a story that has never been told.This surreptitious war began with the Iranian revolution and simmers today inside Iraq and in the Persian Gulf. Fights rage in the shadows, between the CIA and its network of spies and Iran's intelligence agency. Battles are fought at sea with Iranians in small speedboats attacking Western oil tankers. This conflict has frustrated five American presidents, divided administrations, and repeatedly threatened to bring the two nations into open warfare. It is a story of shocking miscalculations, bitter debates, hidden casualties, boldness, and betrayal.A senior historian for the federal government with unparalleled access to senior officials and key documents of several U.S. administrations, Crist has spent more than ten years researching and writing The Twilight War, and he breaks new ground on virtually every page. Crist describes the series of secret negotiations between Iran and the United States after 9/11, culminating in Iran's proposal for a grand bargain for peace-which the Bush administration turned down. He documents the clandestine counterattack Iran launched after America's 2003 invasion of Iraq, in which thousands of soldiers disguised as reporters, tourists, pilgrims, and aid workers toiled to change the government in Baghdad and undercut American attempts to pacify the Iraqi insurgency. And he reveals in vivid detail for the first time a number of important stories of military and intelligence operations by both sides, both successes and failures, and their typically unexpected consequences.Much has changed in the world since 1979, but Iran and America remain each other's biggest national security nightmares. "The Iran problem" is a razor-sharp briar patch that has claimed its sixth presidential victim in Barack Obama and his administration. The Twilight War adds vital new depth to our understanding of this acute dilemma it is also a thrillingly engrossing read, animated by a healthy irony about human failings in the fog of not-quite war.
