Keeping Iraq's Oil In the Ground
"Did Dick Cheney send us in to seize the last dwindling supplies? Unlikely. Our world's petroleum reserves have doubled in just twenty-five years -- and it is in Shell's and the rest of the industry's interest that this doubling doesn't happen again. The neo-cons were hell-bent on raising Iraq's oil production. Big Oil's interest was in suppressing production, that is, keeping Iraq to its OPEC quota or less.
