Death toll of US soldiers in Afghanistan hits 2,000

This is a cold reminder of the perils that remain after an 11-year conflict that now garners little public interest at home.The toll has climbed steadily in recent months with a spate of attacks by Afghan army and police supposed allies against American and NATO troops. That has raised troubling questions about whether countries in the U.S.-led coalition in Afghanistan will achieve their aim of helping the government in Kabul and its forces stand on their own after most foreign troops depart in little more than two years.The tally is modest by the standards of war historically, but every fatality is a tragedy and 11 years is too long, said Michael OHanlon, a fellow at the Brookings Institution in Washington. All that is internalized, however, in an American public that has been watching this campaign for a long time. More newsworthy right now are the insider attacks and the sense of hopelessness they convey to many. Attacks by Afghan soldiers or police or insurgents disguised in their uniforms have killed 52 American and other NATO troops so far this year.We have to get on top of this. It is a very serious threat to the campaign, the U.S. militarys top officer, Army Gen. Martin Dempsey, said about the insider threat.The top commander of U.S. and NATO forces in Afghanistan, Gen. John Allen, was blunter.Im mad as hell about them, to be honest with you, Allen told CBS 60 Minutes in an interview to be broadcast on Sunday. It reverberates everywhere across the United States. You know, were willing to sacrifice a lot for this campaign, but were not willing to be murdered for it.The insider attacks are considered one of the most serious threats to the U.S. exit strategy from the country. In its latest incarnation, that strategy has focused on training Afghan forces to take over security nationwide allowing most foreign troops to go home by the end of 2014.As part of that drawdown, the first 33,000 U.S. troops withdrew by the end of September, leaving 68,000 still in Afghanistan. A decision on how many U.S. troops will remain next year will be taken after the American presidential elections. NATO currently has 108,000 troops in Afghanistan including U.S. forces down from nearly 150,000 at its peak last year.The program to train and equip 350,000 Afghan policemen and soldiers has cost the American taxpayer more than $22 billion in the past three years.The most recent attack came just days after Defense Secretary Leon Panetta said most U.S. and coalition combat units in Afghanistan returned to their practice of partnering with Afghan forces, nearly two weeks after the top U.S. commander put restrictions on such cooperation.Like so many other deaths in Afghanistan, the latest were shrouded in confusion and conflicting accounts.On Sunday, U.S. officials confirmed the deaths of two Americans, a service member and a civilian contractor killed late Saturday.The fighting started when insurgents attacked a checkpoint set up by U.S. forces in eastern Wardak province, said Shahidullah Shahid, a provincial government spokesman. He said the insurgents apparently used mortars in the attack. The Americans thought they were under attack from their allies at a nearby Afghan army checkpoint and fired on it. The Afghan soldiers returned fire, Shahid said.
