Remember a guy named Pablo Escobar? He was ruling Colombia violently for years until the Colombian government (and a group of rebels called Los Pepes) started to get pretty nasty in return. Los Pepes began killing all known associates of Escobar...one time even going so far as to kill an Escobar lawyer and his 16 year old son. That kind of relentlessness was a major reason for his downfall.
BTW how is that War On Drugs going? Have we won that one yet? What's it been about 30 years now, and how much money?
It will be the same with the war on terror. We will always be an oil pig, so we will always live with terrorism. Or the oil will run out.
