With oil, this is something that will change over the next decade as it gets scarcer in North America, and more difficult to extract from the Muslim countries. Add to that, North America's (I include Canada) short sighted policy's towards the Arab world turning them even more against us, and China and India becoming major consumers of oil, I expect the Arab producers will prefer selling closer to home, leaving North America pretty much in the cold with regard to oil imports from the Middle East. The Athabasca tar sands project, while able to produce a pretty huge amount of oil, is extremely dirty. Fully 1/3 of the carbon emmissions that Canada produces is from this project, and it takes 1 barrel of natural gas to produce 2 barrels of oil from the bitumen ore that is being mined. Add to that, it is an environmental disaster, in that it will, eventually, make an area of land the size of Florida completely unusable.
