A tragic story out of Iraq today as a soldier has been arrested for shooting five of his fellow soldiers. We want to avoid too much speculation at this point but early reports do suggest that the suspect was being treated for stress.

This is an increasing problem: as troops are sent back to Iraq over and over again, the stress levels begin to rise. Above and beyond the issues involved in being in combat you now have the stress placed on the families and the worries over that.

Obviously this is not the place to open a debate over Iraq policy, but it is a debate that is increasingly important for us to have.
