I've actually re-looked over your chart a few times before my last post.....
I'm only picking at the part in the small right hand side of your graph where is states the "World Reserves of Oil" which to me seems out dated.... possibly layed out prior to our discovering and production of the Oil Sands......
All I'm saying is we're a bigger and easier target then what your graph shows...... one would think
I'm just saying that hypothetically, what would happen if we cut our supply to the US based on what you said, and the graph I showed?
