On November 8, 2016, Donald Trump won the American presidential election, to the surprise of many across the globe. Now that Trump is Commander-in-Chief of the most powerful country on earth, Americans and non-Americans alike have been left wondering what this will mean for the world. It has been claimed that Trump’s foreign policy views are impulsive, inconsistent and that they were improvised on the campaign trail. However, drawing on interviews from as far back as 1980, Charlie Laderman and Brendan Simms show that this assumption is dangerously false. They reveal that Trump has had a consistent position on international trade and America’s alliances since he first considered running for president in the late 1980s. Furthermore, his foreign policy views have deep roots in American history. For the new President, almost every international problem that has confronted the United States can be explained by the mistakes of its leaders. Yet, after decades of dismissing America’s leaders as fools and denouncing their diplomacy, Trump must now prove that he can do better. Over the past three decades, he has been laying out in interviews, articles, books and tweets what amounts to a foreign policy philosophy. This book reveals the world view that Trump brings to the Oval Office. It shows how that world view was formed, what might result if it is applied in policy terms and the potential consequences for the rest of the world.
