I think we need the energy security for ourselves. But remember, when it comes to crude oil, it is a global market. You should not act unilaterally as a country, because all you'll do is isolate the economics you create with whatever subsidies or other policies you might bring to bear. So you always have to deal with oil from an open, free-market type of perspective.
I'll remind you as well that we are tied to doing this with the United States in our free trade agreement. We do not have the ability to subsidize this business, or withhold exports, etc. So the approach needs to be global.
