Given the current state of our finances, we could sure use a quarter of a trillion dollars a year recycling through the U.S. economy rather than through the economies of Iran, Russia, and Venezuela.

There's no question that tar sands in Canada are probably the largest source of oil available to the U.S. over a long period of time. There's as much oil in the tar sands probably as there is in Saudi Arabia. The problem is, there's a huge capital requirement to develop that.

The older I get, the more I see a straight path where I want to go. If you're going to hunt elephants, don't get off the trail for a rabbit.

We are now spending half a trillion dollars on foreign oil, importing 62 percent of the oil we use, and we haven't had the leadership in D.C. to do anything about it. We've got to move to other sources of energy. But we've gotten way behind, and will continue to pay the fiddler. It's not a good future.

For decades, our dependence on OPEC oil has dictated our national security decisions and tied us up in the Middle East at an incredible price. We've spent more than $5 trillion and thousands of American soldiers have died securing Middle East oil.
