I think sometimes that people think brave means not being afraid, which of course it doesn't mean that at all. It means that you're afraid, but you move past that and do it anyway, do what you think is right.
As a privileged survivor of the First World War, I hope I may be allowed to interject here a deeply felt tribute to those who were not fortunate enough to succeed, but who shared the signal honor of trying to the last to salvage peace.
