Paul Krugman’s New York Times column for Friday, “ Shock Doctrine, U.S.A. ,” used for both headline and text fodder a book of far-left paranoid propaganda by Naomi Klein to push Krugman’s pet idea: That Wisconsin’s Republican Gov. Scott Walker is trying to make a “power grab” in order “to destroy the last major counterweight to the political power of corporations and the wealthy.” Here’s a thought: maybe Madison, Wis., isn’t Cairo after all. Maybe it’s Baghdad — specifically, Baghdad in 2003, when the Bush administration put Iraq under the rule of officials chosen for loyalty and political reliability rather than experience and competence.
