The remarks were a blunt reminder of the gloom underscoring U.S. military assessments of the war between the U.S.-backed Afghan government and the Islamist militant group, classified by U.S. commanders as a "stalemate" despite almost 16 years of fighting.
"We are not winning in Afghanistan right now. And we will correct this as soon as possible," Mattis said in testimony to the Senate Armed Services Committee. Mattis acknowledged that he believed the Taliban were "surging" at the moment, something he said he intended to address.
Some U.S. officials questioned the benefit of sending more troops to Afghanistan because any politically palatable number would not be enough to turn the tide, much less create stability and security. To date, more than 2,300 Americans have been killed and more than 17,000 wounded since the war began in 2001.
The Afghan government was assessed by the U.S. military to control or influence just 59.7 percent of Afghanistan's 407 districts as of Feb. 20, a nearly 11 percentage-point decrease from the same time in 2016, according to data released by the U.S. Special Inspector General for Afghanistan Reconstruction.
