This undated picture issued by Britain's Ministry of Defence, Monday, Aug. 17, 2009, shows Private Richard Hunt from The Second Battalion The Royal Welsh, who has been named as the 200th British soldier to be killed in Afghanistan. Britain's Prime Minister Gordon Brown affirmed Britain's commitment to Afghanistan Sunday, on a weekend in which roadside bombs killed five more soldiers, pushing the U.K. death toll past 200. The grim milestone has reignited debate about the heavy human cost of a conflict the government claims is vital to defeating terrorism but that critics say is unwinnable.
