The Independent of London is reporting Afghan President Hamid Karzai is preparing to announce a timetable for the withdrawal of foreign troops from Afghanistan by 2014. The withdrawal is described in an internal document as “conditions-based and phased.” A formal announcement is expected to come on Tuesday during a major international donors conference in Kabul. The news comes as Vice President Joe Biden is backing down from his previous claims that the US will begin a sizable withdrawal next July. In an interview with ABC News, Biden said he now thinks the pullback could entail “as few as a couple of thousand troops.”
