This book focuses on ascertaining what distinguishes the Cold War that the U.S. sustained with the USSR from the one now emerging with China. By comparing their characteristics, it elaborates on how well prepared the US is to undertake this fresh challenge. In doing so, the book analyses six fundamental differences between both cold wars; ideology, alliances, strategic consistency, military, economics, and containment. While the configuration of factors benefited the US during its first Cold War, they now point in the opposite direction. While the first Cold War was instrumental in projecting the US to the pinnacle, the second can only accelerate its dwindling.
