From the introduction:
After the end of World War II, the victorious allies found their doctrines to be irreconcilably different, and that Communism and Liberal Democracy could not coexist, save as enemies. Thus, the world was split into two -- East and West. This marked the beginning of the era called the Cold War. A war unlike any other in history was then waged- with weapons of mass destruction ensuring a tense standoff, but preventing open warfare between the forces of the world. Endless proxy wars will soon be seen- Across deserts, mountains, and jungles. This is a time of subterfuge, tension, and gray morality. This is the age of spies, guerillas, and of course, your own legacy.
