You need to go farther back in time than the Soviet invasion of Afghanistan. Start with the end of World War II.

These sites should help you.

why do i need to do that? I have to focus on events of the 1970s and 1980s
Blame is usually attached to the beginning of a conflict. However, the articles above detail the Cold War in the 70s and 80s so you should find lots of information there.
