At the beginning of June 1961, the tensions of the Cold War were supposed to abate as both sides sought a resolution. The two most important men in the world, John F. Kennedy and Nikita Khrushchev, met for a summit in Vienna. Yet the high hopes were disappointed. Within months the Cold War had become very hot: Khrushchev built the Berlin Wall and a year later he sent missiles to Cuba to threaten the United States directly. Despite the fact that the Vienna Summit yielded barely any tangible results, it did lead to some very important developments. In The Vienna Summit and Its Importance in International History international experts use new Russian and Western sources to analyze what really happened during this critical time and why the parties had a close shave with catastrophe.
