Nine years into the war on terror and we still don't hear any sound analysis as to why our adversaries fight. The only explanation thus far has been summed up in one word ideology. Ideology is really just a synonym for religion and religion is not why people fight but rather the consolation prize for the loss of one's life in battle.
Anger knows no boundaries. Someone may have hatred toward another but no aggression is usually exhibited. Anger, on the other hand, festers and is self perpetuating. Anger is most often generated when one's space becomes occupied by another. Exploitation or confiscation may also fuel anger. In some cases anger is an inherent trait and not a product of outside circumstances. Anger can become a common bond in which people unite under one cause. This is how the masses come into conflict.
We must better understand human behavior and frailties in finding a solution to our global discord.
