Former Democratic senator Bob Kerrey is making his case for staying the course in Iraq, writing recently in the Wall Street Journal that "... a unilateral withdrawal from Iraq would hand Osama bin Laden a substantial psychological victory."The 9/11 Commission member and Vietnam war veteran tells Bill Moyers why he supported the invasion of Iraq and why he continues to believe that having US military forces in Iraq is necessary in fighting terrorism. Then, with heated debate looming large over progress reports and withdrawal deadlines for Iraq, what's next for Afghanistan? Journalist Christian Parenti, just back from his third visit to the forgotten frontline, speaks to Moyers about the growing influence of warlords in government and the resurgence of the Taliban. And, one of Washington's most influential public advocates talks about what is at stake in the ethical reforms under consideration in Congress.
