To find the real reasons behind conflicts and wars in this world, you need to follow some or all of four things: Money, blood, power or natural resources (usually oil or natural gas but it can be cobalt like in the Congo).
Oil is behind the conflicts in Darfur, Somalia and other similar places.
The war in Afghanistan was never about finding bin Laden. It was about uniting Afghanistan into a single government so a pipeline could be constructed to bring a million barrels a day from areas north of Afghanistan, Turkmenistan, Uzbekistan, Kazakhstan and Russia to markets (http://www.lewrockwell.com/orig/sardi7.html).
We need to stop listening to what the "official" media tells us when it comes to conflicts and wars because the official media is corporate and government owned and/or controlled by government. Less than one percent of the "news" in the world today is reported and what is reported is usually heavily edited and slanted for propaganda purposes.
Governments don't want the world to know that huge genocides are going on just because of oil, gas or other natural resources. The world might get angry as a body and might organize to reject the genocides. Big Oil and Energy doesn't want that to happen because it will interfere with their profits.
