Thank you.
Going back to you, Ms. Mason, I'm curious. You seem to subscribe to a philosophy or an ideology that the only option is diplomacy. It's diplomacy at all costs. You also illustrated where the North Koreans have drawn the line in the sand: they've said that the public will eat grass before giving up. They've made very clear what their position is.
What should our position be in terms of our interest in diplomacy? At what point do we say that we've tried diplomacy, it's not working, and now we need another option? What is our threshold?
