KABUL (AP) -- President Barack Obama has told American forces during his surprise visit to Afghanistan that U.S. lives would be at risk if the Taliban retake control of the country.
Obama says difficult days lie ahead in the 8-year-old war and he says there will be setbacks. But he says the U.S. doesn't quit and will prevail.
The president spoke to about 2,500 U.S. forces at Bagram Air Field after talks earlier Sunday in Kabul with Afghan leaders.
Obama told President Hamid Karzai and his Cabinet that they need to make more progress in fighting corruption and improving their government.
