It was my duty to shoot the enemy and I don't regret it. My regrets are for the people I couldn't save: Marines soldiers buddies. I'm not naive and I don't romanticize war. The worst moments of my life have come as a SEAL. But I can stand before God with a clear conscience about doing my job.
The thing that most attracts me to historical fiction is taking the factual record as far as it is known using that as scaffolding and then letting imagination build the structure that fills in those things we can never find out for sure.
