Contributor(s): Chris Gilson, Dr. Peter Harris | In September 2024 the Phelan US Centre spoke to Peter Harris, Associate Professor of Political Science at Colorado State University about his new book, Why America Can’t Retrench (And How It Might) which looks at the US’ dominant role in the world, how it got there and the factors preventing global restraint. They discuss the idea of America’s ‘primacist’ approach to international affairs and the role of domestic politics and systems in preventing a change to America’s role in the world. This episode was produced by Chris Gilson and Anderson Tan.
