Thank you very much.
Thank you, folks, for being here. I appreciate your feedback.
Ms. Mason, you spoke about the fact that a diplomatic approach was the best bet to end the North Korean threat. I want to talk a bit about sanctions and hear some of your thoughts on them: whether they traditionally work or whether they're working in this particular case with North Korea. If the U.S. were to soften its stance, do you think North Korea would be more open to diplomacy, or would it continue to advance its research and development?
Also, in your opinion, do the last two decisions to ramp up sanctions directly correspond to the proliferation of what North Korea has been actively doing in the last year or so?
