Great powers have a unique capacity to disrupt the global order. No major leader promises to do so as systematically as Donald Trump. 

In a victory that stunned most experts, Trump defeated the experienced Hillary Clinton. He has vowed to tear up free trade agreements, force NATO members to pay their share of expenses, and put American national interests first. If he does what he has promised to do, Trump will disrupt the long-standing liberal international order that western leaders began to build in the ashes of World War II.

Who is Donald Trump? What paved the way for his success in the election? Does his past help to explain his present and predict the future?

David Cay Johnston is uniquely qualified to answer these questions. A Pulitzer Prize-winning investigative reporter, he has reported on Trump for nearly 30 years. Covering the long arc of Trump's career in his new book, The Making of Donald Trump, Johnston tells the story of how a boy from a quiet section of Queens, New York became an entirely new and complex breed of public figure.
