Social knowledge is formed in the light of the variables of civilization, past, present, future, cultural contact, production power and philosophy.All these variables work together to form a cultural pattern that distinguishes the behavior of the society it stems from. However , it is not necessary that all these variables work together or have equal role in knowledge formation . One variable may has priority over others for one reason or another.Undoubtedly, Iraq accupation on April 4th 2003 caused an extreme change in the political map.
