Positing that presidents shape America's foreign policy according to their ethnic heritage, Tom A. Breslin's intriguing new book examines two groups that have dominated the presidency and the distinctly different agendas that have resulted. Does presidential ethnicity really shape American foreign policy? How is American foreign policy determined? The Great Anglo-Celtic Divide in the History of American Foreign Relations (Praeger, $58) approaches that question from a fascinating perspective, arguing that, to a large extent, the answer lies in the ethnicity of the president. To make its point, this book examines the key foreign policies of American presidents from George Washington to George W. Bush and shows how their most important foreign policy decisions have tended to follow an ethnic pattern. Presented in collaboration with Florida International University's School of International and Public Affairs.
