How does the army of a liberal, multicultural and often secular society develop in its soldiers the spiritual resilience to cope with war, to face trauma, death and bereavement, and to fight opponents who have the advantage of a strong and common religious faith?That’s the question the Pentagon has been grappling with, as it confronts the apparent epidemic of post-traumatic stress disorder affecting a fifth of its troops coming home from Iraq and Afghanistan. Its response is a new psychological training programme called Comprehensive Soldier Fitness, which aims to strengthen the emotional, psychological and, yes, spiritual resilience of each of the 1.1 million soldiers serving in the US Army. The person in charge of the $125 million programme is Brigadier-General Rhonda Cornum, herself an unusually resilient person.
