Book excerpt: Something is going badly wrong in America. But what is really happening, why, and what does it mean? Could the US itself now be the greatest threat to the future of the West? In this fascinating account of America today, Patrick Davies, former British Deputy Ambassador to the US, sets out to understand how America, blinded by myths of its own exceptionalism, has failed to tackle serious political, social and economic problems which are exacerbating divisions in its society, poisoning its politics and ultimately fuelling America's decline. The Great American Delusion asks whether, with global power shifting eastwards, the US can save itself and, with it, the Western world before it's too late. Patrick Davies worked alongside the Obama and Trump White Houses for five years. He has more than 30 years' experience of America, its people and its politics.
