The Iraq war was all about oil. The conflict in Iraq between it's inhabitants is all about religion and tribalism. 'We' can never 'fix' this situation, and 'we' should never have gone there in the first place.
Trying to tie tax rates (which are never paid due to cuts, incentives, loopholes and etc) to this is ludicrous.

My figures are from the WSJ and Forbes magazines. Corporations move offshore to shield shareholder dividends, also as reported by Forbes.
