Updated annually and part of the renowned “World Today Series,” USA and the World presents an unusually penetrating look into America and its relationship to the rest of the world.

The U.S. role in the world refers to the overall character, purpose, or direction of U.S. participation in international affairs and the country's overall relationship to the rest of the world. The U.S. role in the world can be viewed as establishing the overall context or framework for U.S. policymakers for developing, implementing, and measuring the success of U.S. policies and actions on specific international issues, and for foreign countries or other observers for interpreting and understanding U.S. actions on the world stage. While descriptions of the U.S. role in the world since the end of World War II vary in their specifics, it can be described in general terms as consisting of four key elements: global leadership; defense and promotion of the liberal international order; defense and promotion of freedom, democracy, and human rights; and prevention of the emergence of regional hegemons in Eurasia. The issue for Congress is whether the U.S. role in the world is changing, and if so, what implications this might have for the United States and the world. A change in the U.S. role could have significant and even profound effects on U.S. security, freedom, and prosperity. It could significantly affect U.S. policy in areas such as relations with allies and other countries, defense plans and programs, trade and international finance, foreign assistance, and human rights. Some observers, particularly critics of the Trump Administration, argue that under the Trump Administration, the United States is substantially changing the U.S. role in the world. Other observers, particularly supporters of the Trump Administration, while acknowledging that the Trump Administration has changed U.S. foreign policy in a number of areas compared to policies pursued by the Obama Administration, argue that under the Trump Administration, there has been less change and more continuity regarding the U.S. role in the world. Some observers who assess that the United States under the Trump Administration is substantially changing the U.S. role in the world-particularly critics of the Trump Administration, and also some who were critical of the Obama Administration-view the implications of that change as undesirable. They view the change as an unnecessary retreat from U.S. global leadership and a gratuitous discarding of long-held U.S. values, and judge it to be an unforced error of immense proportions-a needless and self-defeating squandering of something of great value to the United States that the United States had worked to build and maintain for 70 years. Other observers who assess that there has been a change in the U.S. role in the world in recent years-particularly supporters of the Trump Administration, but also some observers who were arguing even prior to the Trump Administration in favor of a more restrained U.S. role in the world-view the change in the U.S. role, or at least certain aspects of it, as helpful for responding to changed U.S. and global circumstances and for defending U.S. interests. Congress's decisions regarding the U.S role in the world could have significant implications for numerous policies, plans, programs, and budgets, and for the role of Congress relative to that of the executive branch in U.S. foreign policymaking.

INSTANT NEW YORK TIMES BESTSELLER “One of the most important books I’ve ever read—an indispensable guide to thinking clearly about the world.” – Bill Gates “Hans Rosling tells the story of ‘the secret silent miracle of human progress’ as only he can. But Factfulness does much more than that. It also explains why progress is so often secret and silent and teaches readers how to see it clearly.” —Melinda Gates "Factfulness by Hans Rosling, an outstanding international public health expert, is a hopeful book about the potential for human progress when we work off facts rather than our inherent biases." - Former U.S. President Barack Obama Factfulness: The stress-reducing habit of only carrying opinions for which you have strong supporting facts. When asked simple questions about global trends—what percentage of the world’s population live in poverty; why the world’s population is increasing; how many girls finish school—we systematically get the answers wrong. So wrong that a chimpanzee choosing answers at random will consistently outguess teachers, journalists, Nobel laureates, and investment bankers. In Factfulness, Professor of International Health and global TED phenomenon Hans Rosling, together with his two long-time collaborators, Anna and Ola, offers a radical new explanation of why this happens. They reveal the ten instincts that distort our perspective—from our tendency to divide the world into two camps (usually some version of us and them) to the way we consume media (where fear rules) to how we perceive progress (believing that most things are getting worse). Our problem is that we don’t know what we don’t know, and even our guesses are informed by unconscious and predictable biases. It turns out that the world, for all its imperfections, is in a much better state than we might think. That doesn’t mean there aren’t real concerns. But when we worry about everything all the time instead of embracing a worldview based on facts, we can lose our ability to focus on the things that threaten us most. Inspiring and revelatory, filled with lively anecdotes and moving stories, Factfulness is an urgent and essential book that will change the way you see the world and empower you to respond to the crises and opportunities of the future. --- “This book is my last battle in my life-long mission to fight devastating ignorance...Previously I armed myself with huge data sets, eye-opening software, an energetic learning style and a Swedish bayonet for sword-swallowing. It wasn’t enough. But I hope this book will be.” Hans Rosling, February 2017.

The United States has been the world's dominant power for more than a century. Now many analysts believe that other countries are rising and the United States is in decline. Is the unipolar moment over? Is America finished as a superpower? In this book, Michael Beckley argues that the United States has unique advantages over other nations that, if used wisely, will allow it to remain the world's sole superpower throughout this century. We are not living in a transitional, post-Cold War era. Instead, we are in the midst of what he calls the unipolar era—a period as singular and important as any epoch in modern history. This era, Beckley contends, will endure because the US has a much larger economic and military lead over its closest rival, China, than most people think and the best prospects of any nation to amass wealth and power in the decades ahead. Deeply researched and brilliantly argued, this book covers hundreds of years of great power politics and develops new methods for measuring power and predicting the rise and fall of nations. By documenting long-term trends in the global balance of power and explaining their implications for world politics, the book provides guidance for policymakers, businesspeople, and scholars alike.
