Richard Haass and Mitchell Reiss, as autonomous diplomats in the George W. Bush State Department, were able to alter US intervention in Northern Ireland and play critical roles in the post-1998 peace process. Their contributions have not been fully appreciated or understood. The restoration of Northern Ireland’s power-sharing government in 2007 was made possible by State Department-led intervention in the peace process. There are few references to Northern Ireland in work examining the foreign policy legacy of the George W. Bush presidency. Moreover, the ability to control US foreign policy towards the region brought one of George W. Bush’s Northern Ireland special envoys into direct diplomatic conflict with the most senior actors inside the British government. This book will uncover the extent of this fall-out and provide original accounts on how diplomatic relations between these old allies became so fraught.
