From the blog "What is really going on"

There has been lots of rift between the Saudis and Qatar, for quite some time. Saudi Arabia is accusing Qatar of financing terrorism. The Saudis are trying to give Qatar lots of problems, and Qatar fought back, by damaging OPEC and leaving. This will be the beginning of the unraveling of OPEC as I predict more nations to leave OPEC. This will also give OPEC less control of oil prices. Therefore any production cuts from OPEC in the future could soon become meaningless.
