President Barack Obama said Wednesday there will be no quick decision on whether to send more U.S. troops into the widening war in Afghanistan, saying «my determination is to get this right.», AP reported. The president's comments came one day after Adm. Mike Mullen, his top military adviser as chairman of the Joint Chiefs of Staff, endorsed an increase in U.S. forces as likely necessary to battle a deepening insurgency. The U.S. and NATO commander in Afghanistan, Gen. Stanley McChrystal, also has delivered a grim assessment of the war and is expected to follow up soon with a request for thousands of additional troops. The president has already ordered 21,000 more troops to Afghanistan, increasing the U.S. commitment there to 68,000 by year's end. Yet violence in Afghanistan has soared to record levels. More U.S. troops _ 51 _ died in Afghanistan in August than in any other month since the U.S.-led invasion in October 2001. -- SPA
