This book revisits the economic relationship that ties the UK and Ireland to the United States in the aftermath of the greatest economic crisis of the past fifty years. When considering recent developments to these economic links, it appears that oppositional forces are at work. On one hand, globalization and the rise of new economic powers may undermine the ties. Besides, Ireland and the UK European Union membership could also loosen their economic ties with the US. Conversely, the future Transatlantic Trade and Investment Partnership agreement may well strengthen trade and investment links between the US and Europe. Are the economic bonds between the US, the UK and Ireland waning, as some pundits purport? Or are those claims overstated? Could their economic relationship simply be going through a process of change? Although there may not be a single and straightforward answer to these questions, the authors seek to address these issues and provide insight into the changing dynamics of this historic economic relationship.
