Even for American oil consumers, doesn’t fewer imports imply an expectation of greater stability going forward, since the price is more dependent upon just this country’s happenings, and less dependent on the happenings inside other countries? Or can it be argued either way, e.g. that if the production was spread over more countries the prices would be less dependent on any one country in isolation?
