Study of the Cold War all too often shows us the war that wasn’t fought. The reality, of course, is that many “hot” conflicts did occur, some with the great powers' weapons and approval, others without. It is this reality, and this period of quasi-war and semiconflict, that Jonathan M. House plumbs in A Military History of the Cold War, 1962–1991, a complex case study in the Clausewitzian relationship between policy and military force during a time of global upheaval and political realignment.
