A lesson giving context about the tense 1962 standoff between the United States and the Soviet Union that nearly resulted in nuclear war.

Most historians agree that the world has never come closer to nuclear war than it did during a thirteen-day period in October 1962, after the revelation that the Soviet Union had stationed several medium-range ballistic missiles in Cuba. This lesson will examine how this crisis developed, how the Kennedy administration chose to respond, and how the situation was ultimately resolved.

Cultural or spatial diffusion is the process of the spread of an idea or innovation from one culture to another. This process is more likely to occur from cultural hearths, or centers of culture that are closer in proximity to each other. With the rise of globalization and technology the spread of culture is more prevalent than ever before. Barriers to cultural diffusion include time and distance it takes for the ideas to travel, known as time distance decay, as well as the prevailing attitudes and taboos which might hinder the adoption of new culture. South Korea is an ideal case study to examine both elements of unique culture and cultural diffusion. Sometimes described as the “shrimp between two whales,” and a dominant economic power in Asia, South Korea is no stranger to the forces of foreign influence and cultural diffusion. Yet as a modern industrialized country who has embraced globalization, they have also maintained many elements of vibrant and unique culture. In examining South Korean culture, both of these trends can be readily observed.
