A couple of minor points
...the oil we pump domestically isn't any cheaper than the stuff we import, is it?
The price of oil is far higher than is justified by the cost of getting it. Concerns about the stability of the producing nations is no small part of this. The falling dollar isn't helping, either. It's hard to believe that opening new domestic sources wouldn't do something to alleviate this.
Most of the North Slope oil went to Japan, we didn't burn it here.
The amount of crude exported out of the country from Alaska has never exceeded 7 percent, and that during a five-year period from 1995 to 2000.
