FILE - In this May 16, 1988 file photo, a convoy of tanks and armored personnel carriers roll out of Kabul, heading north back to the Soviet Union.  The US military presence in Afghanistan has surpassed the Soviet occupation of the country. The Soviet Union couldn't win in Afghanistan, and now the United States is about to have something in common with that futile campaign: nine years, 50 days. The U.S.-led coalition has now been fighting for as long as the Soviets did, and while two invasions had different goals _ and dramatically different body counts _ whether they have significantly different outcomes remains to be seen.
