A look at the differences expressed by the U.S. top commander and top U.S. diplomat in Afghanistan during the Obama administration's three-month review of strategy for the war:
_U.S. Afghanistan Ambassador Karl Eikenberry, a retired general who once commanded troops in Afghanistan, early last month questioned the wisdom of sending more troops. Eikenberry urged the Obama administration to step cautiously in planning any major buildup while there are still so many questions surrounding Afghan President Hamid Karzai, the U.S.-backed leader whose administration has been stained by corruption and mismanagement.
_The top U.S. and NATO commander in Afghanistan, Gen. Stanley McChrystal, asked for about 40,000 additional forces to accomplish the mission of protecting the Afghan population, beating back the insurgency and ultimately ending the 8-year-old war.
President Barack Obama is sending 30,000 U.S. troops and NATO has pledged 7,000.
