British Prime Minister Gordon Brown (L) talks to a member of the RAF Regiment as he arrives for a service of commemoration to mark the end of the combat operations in Iraq, at St Paul's Cathedral, in London, on October 9, 2009. The Archbishop of Canterbury criticised policymakers Friday for failing to properly consider the human cost of the Iraq war, at a ceremony attended notably by former British premier Tony Blair. In a service to mark the loss of 179 British troops in the conflict, Rowan Williams reminded his audience at London's St Paul's Cathedral of the divisions caused by the military campaign to depose Saddam Hussein.
