The Cold War dominated world history for nearly half a century, locking two superpowers in a global rivalry that only ended with the Soviet collapse.

In Summits, eminent diplomatic historian David Reynolds takes us alongside the statesmen who stood, if only briefly, on top of the world, offering valuable lessons as we find ourselves confronting once again a war without end.
