Of course, I can recommend you a book on economics and international relations that covers American history from 1877 to the present. This book was Modern History of the United States by Cyrus Hayes (68 years old, USA). It was divided into three parts: the early history, the war experience, and modern history of the United States. This translation should be your ideal choice to use your power. It foretells the most important and most experienced events in American history and provides a wealth of historical data and perspectives.
