On empire : America, war, and global supremacy by E J Hobsbawm

"With his usual measured and brilliant historical perspective, Eric Hobsbawm traces the rise of American hegemony in the twenty-first century. He examines the state of steadily increasing world disorder in the context of rapidly growing inequalities created by rampant free-market globalization. He makes clear that there is no longer a plural power system of states whose relations are governed by common laws--including those for the conduct of war. He scrutinizes America's policies, particularly its use of the threat of terrorism as an excuse for unilateral deployment of its global power." - Editorial Reviews
