In countries where we have closed our missions—for example, in North Korea or Iran—we work through protecting powers, through a like-minded state that's agreed to serve as our representative on the ground. We also work through many different avenues. For example, in relation to your previous question, when there are no local authorities on the ground or when we need to find alternative avenues of communication, we can work through international organizations or non-governmental organizations. As an example, the International Committee of the Red Cross is an effective advocate on behalf of those who are in detention.
