Thinking more and more about this part of the story, I think I'll let Spencer Tracy from "Judgement at Nuremberg" speak for me as to Giles and the others actions-

There are those in our country today, too, who speak of the "protection" of the country. Of "survival". The answer to that is: *survival as what*? A country isn't a rock. And it isn't an extension of one's self. *It's what it stands for, when standing for something is the most difficult!* Before the people of the world - let it now be noted in our decision here that this is what *we* stand for: *justice, truth... and the value of a single human being!*

Shame Giles
