This New Yorker article, Pump Dreams, by John Cassidy, treads a little delicately around the core reason for the invasion of Iraq and why "retreat is not an option". It's certainly worth a read- the Bush/Cheney oil baron clique- right out of Dallas, in a stupid kinda way- are not about to raise taxes on gas, or mandate better mpg for cars and light trucks. But high oil prices are likely to do what they lack the guts or foresight or common sense for.
Global warning.... what globe? Isn't the earth flat, like texas?
