The rights and wrongs of British intervention in Iraq in 2003 are about to get what one can only hope will be the their definitive airing, as the Chilcot Inquiry finally goes into its last lap. I understand that those about to be criticized — officials, commanders, Tony Blair — are about to get letters of notification. Then the report goes to No 10. The Prime Minister will choose when to publish, which could be some time next year, obviously with an eye on electoral advantage. But publish he must. The subtext to the Whitehall discussion is that never again will UK forces get involved in such tangled, lengthy, and often confused operations.
