I'm delighted for a response.
Firstly, he didn't intend to get caught, he had the misfortune to place his trust in someone who wasn't trustworthy, Adrian Lamo.
More than that he should have led his defence with the Nuremburg defence. Plenty of Nazis met the hangman for saying they were only obeying orders, but after three years of incarceration, 11 months in solidarity, and stripped naked, his resolve was broken.
But most significant of all, his oath of alllegience, when he signed up, explicit ordered him to disobey orders which contravened the Geneva Convention. Indeed he was obligated by that oath to report breaches of the Geneva Convention.
