The history of oil is a chapter in the story of Europe's geopolitical decline in the twentieth century. During the era of the two world wars, a lack of oil constrained Britain and Germany from exerting their considerable economic and military power independently. Both nations' efforts to restore the independence they had enjoyed during the Age of Coal backfired by inducing strategic over-extension, which served only to hasten their demise as great powers. Having fought World War I with oil imported from the United States, Britain was determined to avoid relying upon another great power for its energy needs ever again. Even before the Great War had ended, Whitehall implemented a strategy of developing alternative sources of oil under British control. Britain's key supplier would be the Middle East - already a region of vital importance to the British Empire - whose oil potential was still unproven. As it turned out, there was plenty of oil in the Middle East, but Italian hostility after 1935 threatened transit through the Mediterranean. A shortage of tankers ruled out re-routing shipments around Africa, forcing Britain to import oil from US-controlled sources in the Western Hemisphere and depleting its foreign exchange reserves. Even as war loomed in 1939, therefore, Britain's quest for independence from the United States had failed. Germany was in an even worse position than Britain. It could not import oil from overseas in wartime due to the threat of blockade, while accumulating large stockpiles was impossible because of the economic and financial costs. The Third Reich went to war dependent on petroleum synthesized from coal, domestic crude oil, and overland imports, primarily from Romania. German leaders were confident, however, that they had enough oil to fight a series of short campaigns that would deliver to them the mastery of Europe. This plan derailed following the victory over France, when Britain continued to fight. This left Germany responsible for Europe's oil requirements while cut off from world markets. A looming energy crisis in Axis Europe, the absence of strategic alternatives, and ideological imperatives all compelled Germany in June 1941 to invade the Soviet Union and fulfill the Third Reich's ultimate ambition of becoming a world power - a decision that ultimately sealed its fate.

'Oil and the Great Powers' examines how oil shaped British and German grand strategy in the era of the two world wars, arguing that both countries' efforts to become energy-independent led them to pursue policies that compromised security by inducing strategic over-extension, thereby hastening their decline as great powers.

Great Powers and Regional Orders explores the manifestations of US power in the Persian Gulf and the limits of American influence. Significantly, this volume explores both the impact of US domestic politics and the role played by the region itself in terms of regional policy, order and stability. Well organized and logically structured, Markus Kaim and contributors have produced a new and unique contribution to the field that is applicable not only to US policy in the Persian Gulf but also to many other regional contexts. This will interest anyone working or researching within foreign policy, US and Middle Eastern politics.

Black Gold and Blackmail seeks to explain why great powers adopt such different strategies to protect their oil access from politically motivated disruptions. In extreme cases, such as Imperial Japan in 1941, great powers fought wars to grab oil territory in anticipation of a potential embargo by the Allies; in other instances, such as Germany in the early Nazi period, states chose relatively subdued measures like oil alliances or domestic policies to conserve oil. What accounts for this variation? Fundamentally, it is puzzling that great powers fear oil coercion at all because the global market makes oil sanctions very difficult to enforce. Rosemary A. Kelanic argues that two variables determine what strategy a great power will adopt: the petroleum deficit, which measures how much oil the state produces domestically compared to what it needs for its strategic objectives; and disruptibility, which estimates the susceptibility of a state's oil imports to military interdiction—that is, blockade. Because global markets undercut the effectiveness of oil sanctions, blockade is in practice the only true threat to great power oil access. That, combined with the devastating consequences of oil deprivation to a state's military power, explains why states fear oil coercion deeply despite the adaptive functions of the market. Together, these two variables predict a state's coercive vulnerability, which determines how willing the state will be to accept the costs and risks attendant on various potential strategies. Only those great powers with large deficits and highly disruptible imports will adopt the most extreme strategy: direct control of oil through territorial conquest.

Explains the relationship between oil and war in six different regions worldwide.

Victor McFarland challenges the view that the U.S.-Saudi alliance is the inevitable consequence of American energy demand and Saudi Arabia's huge oil reserves. Oil Powers traces the growth of the alliance through a dense web of political, economic, and social connections that bolstered royal and executive power and the national-security state.
