On The DMZ, Bill and Matt want to see some introspection from conservatives who supported the Iraq War and are now urging intervention. Matt thinks the neoconservative perspective may well be right, and Bill makes the case that ISIS is a threat that the US needs to confront. Is a partition of Iraq a likely outcome of the current violence? On the domestic front: Is Senator Thad Cochran going to lose his primary because he delivered too much bacon to Mississippi? Bill argues that Bernie Sanders is the most relevant potential primary challenger to Hillary Clinton. Plus: Matt defends the name of the Washington Redskins.
