In this March 5, 2003 broadcast, two weeks before the invasion of Iraq, Yale economist William Nordhaus was ridiculed for predicting a war with Iraq might cost as much as $750 Billion in war costs, $2 Trillion to the economy overall, and create $75 a barrel oil with $3 a gallon gas.

And in all this, he still didn't count military rehab or increased domestic security costs, so even HIS estimate was low!
