"[An] epic account...One reason Mr. Westad's narrative is so strong is its use of fresh archival sources from across the globe...How Big Was the Cold War? is easy to answer: It was huge, as this book demonstrates, not only because of the perilous stakes but also because of the size of the two main actors. How Deep Was the Cold War? is also easy to answer, and Mr. Westad does that so very well, showing how it reached into so many places in the world that were a long way from the Berlin Wall."
"An account of the Cold War that is truly global in its scope... a wise and observant history... It also arrives at a moment when we must grasp the dynamics of the Cold War if we want to understand some of today's most urgent developments, from North Korea's acquisition of long-range nuclear missiles to the rise of socialist movements in Western democracies."
"The Cold War evinces a lifetime of research and thought on the subject. Compelling ideas and valuable insights appear frequently."
