Washington: A top American lawmaker has asked Defence Secretary Leon Panetta to create an independent study group on Afghanistan and Pakistan to review the US strategy in the region.

This call by Congressman Frank Wolf follows a report by Army Lt Colonel Daniel Davis which accuses the military of painting a misleading picture of the war in Afghanistan.

Army Lt Col Daniel Davis in an article in the Armed Forces Journal said that no progress is being made in Afghanistan.

"I am deeply troubled by the conclusions reached in Col Davis' assessment and believe that it further underscores the importance of immediately creating the Afghanistan/Pakistan Study Group," Wolf said in his letter to Panetta.

Wolf, author of the legislation that created the Iraq Study Group (ISG), has been pushing the Obama Administration to undertake an outside review of the war in Afghanistan for nearly 18 months.

He successfully added a provision to 2012 defence spending bill allowing for the creation of an outside review of US strategy in Afghanistan and Pakistan and has been urging Panetta, who served on the ISG, to move quickly to set up the panel.

"In the interest of the soldiers, sailors, airmen and Marines serving – and in many cases dying – in Afghanistan, I implore you to immediately establish the Afghanistan/Pakistan Study Group," Wolf said.

Wolf's letter comes in the days after the article by Davis, who in 2010 and 2011, traveled to Afghanistan on assignment with the Army's Rapid Equipping Force.

"What I saw bore no resemblance to rosy official statements by US military leaders about conditions on the ground," Davis wrote in an opinion piece titled 'Truth, lies and Afghanistan', published online on February 5 by Armed Forces Journal.
