The Free Sea offers a unique, single-volume analysis of incidents in American history that affected U.S. freedom of navigation at sea. The book spans more than 200 years, beginning in the Colonial era with the Quasi-War with France in 1798 and extending to contemporary Freedom of Navigation operations in the South China Sea. Through wars and numerous crises with North Korea, North Vietnam, Cambodia, Iran, Russia and China, freedom of navigation has been a persistent challenge for the United States, a nation reliant on open seas for economic prosperity, military security and global order. This volume focuses on the struggle to retain freedom of the seas. Challenges to U.S. warships and maritime commerce have pushed, and continue to challenge, the United States to vindicate its rights through diplomatic, legal, and military means, underscoring the need for the strategic resolve in the global maritime commons.
