I'll respond in English, if I may.
Just to reiterate what has been said and what Christine has I think mentioned as well, the experience of the last 70 years or so has shown that when there are perceived or actual threats of hostility against North Korea, the reaction there has actually been to increase national security measures to increase repression against its own citizens.
The inverse is also true, that when the rhetoric has been toned down, when it was dialled back during the “sunshine policy”, when there have been opportunities for connection, then the actions around national security and the repression of citizens have been decreased.
Yes, I think you're right. The strategy of sanctions and isolation has not reached the desired goal; it hasn't helped with denuclearization. It has further isolated North Korea. Certainly we know that it has harmed the most vulnerable, and I don't think it's getting us anywhere closer to the goal of a more peaceful peninsula.
Certainly all stick and no carrot is not helping. In January, the maximum pressure was all stick; there was absolutely nothing there for the North Korean leadership to grasp on to. As Christine was saying, there is strong support in South Korea for inter-Korean dialogue, for engagement, for cooperation, for development of mutual and respectful engagement. Yet as we know in most of our own relationships, whether they be family, community, or otherwise, if it's all stick and no dialogue, no negotiation, it's very hard to bring people to the table.
