Examining perspective is the process by which you take an event, a circumstance, or even a place and you evaluate them through examination of characteristics and even emotions and feelings generated in you. A perspective is precisely the way in which you interpret information around you depending on certain aspects like your culture, education, customs and traditions, among other things. In the case of the Cold War and what was used during it, as well as the events that took place, an examining perspective might affect the way that you perceive the events of this time period because it would lead you to understand in a different way what happened and the reasons behind it. So, for example, the circumstances of espionage that led to many confrontations during the Cold War between the U.S and Soviet Union. Culturally, and through education, we have been taught that espionage was wrong and brought many problems with it, not least of which might have been a nuclear confrontation. But through an examining perspective, you take much more than just what you can see, hear, touch and taste and you evaluate every aspect, and understand the when and the why of an event.
