Answer:
This is entirely opinionated, but I'll remind you how much tension the Cold War brought. You can answer it either as a citizen or a world leader, I think.
Explanation:
The Cold War brought fear into practically everyone. Everyone was second guessing their friends, families, neighbors, even bosses to being Communist spies. The fear of someone, even in the government, being a spy wreaked havoc in society. Television began broadcasting commercials of what to do if your neighbor is a spy, there were advertisements in the paper, you couldn't go anywhere without being reminded of the Cold War. No Russian was trusted at this time. Not to mention there was the fear of a nuclear attack. There were fallout shelters made in people's homes, schools, and community gathering places. Cartoons were made for children to teach them what they should do if a nuclear warhead were to hit. It was basically Hell.
The US and USSR engaged in nuclear arms race because each country was afraid of the other gaining nuclear supremacy.
The geographic feature that most directly influenced the development of Greek city-states was 2. its mountainous terrain. Greece is a series of island separated by sea and marked with numerous mountains. These mountains kept the region from ever becoming completely unified in ancient times because of the difficulty it took to get from point A to point B. Instead, these mountains resulted in the formation of city-states, smaller political units centered around a single city but sharing a culture similar to other city-states in the area. They were connected by culture rather than politics.
