Look at Iraq, Syria, Lybia, Afghanistan and even the Ukraine and spot the similarities. They all have oil, or major transit corridors running directly to those important fossil fuels, our worlds most valuable commodity. Mark my word, Iran will be next because its sitting on the worlds 2nd biggest gas reserve and Washington is not going to just sit there and tolerate those silk roads between Iran and Pakistan which are being supported and funded by Russia and the worlds biggest oil consumer China.
Black gold will always ensure we intrude into other countries back yards because like it or not, we live in an energy centric world
