A shooting yesterday at Fort Hood in Texas has left 13 people dead – and it has America thinking about the effects of war.

The shooter, Major Nidal Hasan, is a psychiatrist, who reportedly did not want to be deployed overseas – after counseling scores of colleagues coming back from Iraq and Afghanistan, and helping them cope with their post-traumatic stress disorder.

Today, where we live, we’ll talk with an Iraq war veteran, who talks about his experiences in the Middle East and how he uses writing to deal with the wounds of war.

Also National security expert Scott Bates was scheduled to be in Afghanistan as an election observer. Coming up, he'll talk about the canceled elections and the future of Afghanistan, as well as his recent trip to Iraq.
