Sen. Bernie Sanders and Brave New Films have produced another episode of their "Unfiltered" web video series.  This time, they take on the war in Afghanistan. "What I'm not hearing is the national debate about what our exit strategy is going to be (in Afghanistan).  We've been there now for eight years - how many more years will we be there.  What are our goals? Originally we went in there to find Osama bin Laden, we have not accomplished that.  Is it our goal to rebuild a very primitive poor society which has long resisted intervention, which has one of the highest illiteracy rates?  Are we going to create a Jeffersonian democracy there, is that our goal?  I think not," Sanders said in response to a video question from singer-songwriter and political activist Billy Bragg.  Record a question and submit it here.
