NATO says the top commander of U.S. and NATO troops in Afghanistan has finished his 60-day strategic review of the war and that it is now being sent up the chain of command to the Pentagon and NATO headquarters. A NATO statement released Monday said U.S. Gen. Stanley McChrystal reports the situation is «serious» but that success is achievable. McChrystal says success demands a revised strategy, commitment and resolve, according to a report of The Associated Press. NATO says the assessment was requested by the U.S. Secretary of Defense Robert Gates and NATO headquarters. NATO officials say the review does not ask for more troops, an issue that will be considered separately.
