Saddam Hussein planned to start selling oil in currencies other than worthless Federal Reserve Notes (dollars). The Bush regime acted swiftly by fabricating “weapons of mass destruction” lies which were used as a pretext to illegally invade Iraq and assassinate Hussein. WMD’s were never found in Iraq, obviously. The only WMD they possessed was their imminent contribution to the destruction of the already doomed dollar.
Iran has been planning on doing the same thing with their oil bourse for years. After many delays the first phase was opened in 2008. The second phase opened just a few short months ago. Thus the reason for the increased war-mongering against Iran as well as calls for tougher sanctions.
The only thing keeping the dollar alive is the demand created due to the reserve status it enjoys in oil trades. The empire is desperate.
