Chapter 3: the cold war and the age of mutually assured destruction. Between two superpowers and their allies and client states. A war of diplomacy, ideological rhetoric, arms races, and proxy wars. For other countries, the cold war is how they made their international moves. Countries started aligning with either of the super powers. Nonaligned movement - a group of countries (india, indonesia, egypt) seeking to distance themselves from all of it. Themes consistent in history until the collapse of the soviet union. Both superpowers stuck to their beliefs but sacrificed ideological principles if their geopolitical ally ships demanded it. Cold war seeds planted in the latter half of ww2. Soviet union wanted the heartland (re: mackinder) but from their perspective it would be difficult because they are virtually surrounded. To contain them, the us wanted to defend a perimeter around the heartland. Canada joined the us with a bunch of security agreements, like the north.
