I dont complain because what will that get me? Will it make him any less tortured?

War is hell - i say give back 100 times what they give us.
You're missing the point, purposely? Probably.

Not only are you opening up your own troops to similar treatment without recourse to complaint through the Geneva convention, but who is going to surrender to someone who is going to torture them? Don't get me wrong the only reason I would have campaigned for the return of the British prisoners from GB would have been to try them as traitors, but they still have rights as citizens until that trial.

As for giving back 100 times, the days of the Great Khan burning cities and slaughtering all the inhabitants as an abject lesson to future combatants are long gone.
