Growing up in the 1970s and ’80s, the shadow of war hung over us in a way that it’s very difficult for people born after 1990 to understand. There really was a constant sense that the missiles might start flying, whether by intent or mistake made little difference, and the world, well, end. With the vast nuclear arsenals both sides had, that really would have been it.

But then, it was all over. I remember watching it on TV. Solidarity in Poland. Glasnost. Then, marvel of marvels, the Berlin Wall being pulled down, brick by brick, on live TV. The old Soviet order vanished with barely a whimper and hardly any lives lost and… it was over. The confrontation that had defined the half century since the end of World War II was done, basically without a shot being fired.

Or so it seemed. In reality, there had been a series of proxy wars, low-level conflicts, and ideological confrontation throughout the Cold War and, in this book Robert McMahon does a fabulous job of lifting those perilous times out of the memory hole into which we seem determined to cast them.

I don’t really know why that is the case. Looking back, it still seems little less than miraculous that we got away with it. Indeed, so miraculous was the escape that it seems to me that we have almost deliberately forgotten about it, as if to really remember those times would be in some way to acknowledge the irruption of the totally unexpected in human affairs. In most cases when this happens it’s a catastrophe but this was, as Tolkien termed it, a eucatastrophe, the unexpected turn where everything turned out all right. We humans, we are uncomfortable in the presence of the miraculous; we turn away from it. In this case, we have turned away from the history of those years.

McMahon’s short book does a great job of bringing those years back into focus, maintaining the consistent excellence of these Oxford Very Short Introductions. An excellent book.
