“DANGER CLOSE”: One of the most intrepid war reporters I know, Alex Quade, who shepherded me around the Persian Gulf region in the fall of 2002 during the run-up to the Iraq invasion, premieres her feature-length documentary, “Danger Close,” tonight at the National Press Club. The movie, which hits theaters April 28, takes you behind the scenes and puts you on the front lines with U.S. special operations commandos in Afghanistan and Iraq. Tonight’s premiere screening will be followed by a question and answer session with Quade.
