Congressman Ed Markey said today:
Well, we’re in Libya because of oil. And I think both Japan and the nuclear technology and Libya and this dependence that we have upon imported oil have both once again highlighted the need for the United States to have a renewable energy agenda going forward.
Could that possibly explain why we’re not letting the Arab League states take care of Libya?
And according to French intelligence officers, the U.S. wanted to run an oil pipeline through Afghanistan to transport Central Asian oil more easily and cheaply. And so the U.S. told the Taliban shortly before 9/11 that they would either get “a carpet of gold or a carpet of bombs”, the former if they greenlighted the pipeline, the second if they didn’t. See this, this and this.
