Stop the madness!
Make Canada refine it's product, and not allow it to be 'piped' anywhere. There is enough in North America to supply all of our needs. Not only would the price of gasoline/diesel/natural gas/propane drop, there would then be no energy shortages. The middle east could do their own thing, and no longer be a worry to the west. They would fade into obscurity, and not have the wealth that we are providing them (and their terrorist activities) with.
