Blood and Oil by Michael T. Klare explores the geopolitical and economic implications of the United States' growing dependence on foreign oil. Written in the early 2000s, the book outlines the global struggles for control of oil resources and the environmental, economic, and political risks involved. Klare discusses how access to oil has influenced international conflicts, particularly in the Middle East, and highlights the dangers posed by reliance on oil-rich countries with unstable or authoritarian governments. The book argues for the need for alternative energy solutions and a more sustainable energy future, as well as a reevaluation of the political and military interventions associated with securing oil supplies.
