Culprit of the week: So who is behind the Iraqi insurgency this week? Alas it is not Iranian revolutionary guards, Saddam's briefcase, `Udayy Saddam Husayn, the head of former Iraqi mukhabarat, `Izzat Ad-Duri, Syria, Libya, the Ba`th party organization in Damascus, Zarqawi, which is what was reported previously. This week, officials are accusing Hizbullah (never mind that the Zarqawi insurgents are fundamentally hostile to all Shi`ites). OK.
