London ? In an echo of a time when things were going from bad to worse in Iraq, Defense Secretary Robert Gates said Thursday the Bush administration is reviewing its war strategy in Afghanistan amid spreading insurgent violence, rising U.S. and allied military deaths and doubts about winning.

With only a few months left before President Bush leaves office, the administration apparently is attempting to draw a clearer picture for the next commander-in-chief of what needs to be done to stabilize the country, to sustain and increase international support and to make the most of U.S. and allied military forces.

Any changes in strategy now being contemplated would not be as substantial as Bush’s decision in January 2007 to take a fundamentally different approach in Iraq, Pentagon press secretary Geoff Morrell said. Bush added more than 21,000 combat troops in Iraq and endorsed an overhaul of military strategy.

“Nothing of that magnitude” is being considered for the war in Afghanistan, Morrell cautioned.
