“This book makes multiple contributions, and while in no way exhaustive, I want to recognize three of them. … This is an ambitious book. … Those who study and/or practice diplomacy (and public diplomacy) will likely extract the most value from this book. It is an advanced analysis, and while it is well-written, the content is intensely packed together. … The book also serves as a springboard for further research and ideas for honing the practice.” (Katherine A. Brown, Journal of Public Diplomacy, Vol. 4 (1), 2024)“The book takes readers from the foundational experiences of the colonial American frontier, through the maturing of the Republic to the multiple global outreach campaigns waged during the twentieth century, into our own era of digitally powered diplomacy. … This is a book for the ages which belongs at the right hand of every scholar and practitioner with an interest in diplomacy’s public dimension.” (Nicholas J Cull, Place Branding and Public Diplomacy, Vol. 20 (4), December, 2024)
