Someone can correct me if I'm wrong, but it is my understanding that when the North Vietnamese were forcing American POWs to make public statements denouncing the US, the official military policy was to tell American soldiers to do what they are told by their captors; the important thing was to survive the ordeal and eventually return home.
I'm a little hesitant to say what people should do as a point of honor; honor is such a personal thing that I would feel uncomfortable attempting to insist on why I feel is right.
I would have respect for people who, as a matter of honor, would refuse to make these kinds of statements. But I also have respect for people who, in this kind of situation, did what they felt they had to in order to get through it. (By the way, I did not see any of these videos myself.)
That's how I feel about it. One could make the argument, perhaps, that people who join the Royal Marines agree to abide by a certain code of honor, but I'm not a Royal Marine and so it is not my place to criticize them for such a breech.
