"So yeah, this is a very serious issue, and my own guess is that if we ever get the secret documents about the planning for the Iraq war, my expectation is that these considerations will have entered significantly. As to when you get a peak for OPEC, that's farther off - decades, but it's certainly real. There's another side to this, there's a sense in which it's advantageous if the oil peak is earlier. The reason why is it will compel the world, primarily the U.S. here, to move toward something like sustainable energy. If there's unbounded amounts of hydrocarbons, we're just going to destroy the environment for human life or most biological life, so the earlier the peak is, in some respects - yes, it could be catastrophic, it could also be beneficial.
