This book attempts to explain why despite widespread popular support (the "Greek Fire") in the United States of America for the Greek Revolution, the promulgation in 1823 of the Monroe Doctrine led to Washington D.C.'s non-recognition of the Hellenic efforts. It examines the origins and tradition of the diplomatic doctrine of neutrality and argues that the Monroe Doctrine represents its full realization. The new foreign policy doctrine is placed within its proper diplomatic framework, while the role of Secretary of State John Quincy Adams is highlighted. What remains remarkable, is how high on the U.S. policy agenda the Greek War of Independence was and how close it came to being politically vindicated. The epilogue of this book demonstrates based on specific historical episodes, that the "Greek Fire" and the Monroe Doctrine set in many ways the political framework that came to define Hellenic-American relations for almost the next two centuries.
