Thank you very much, Mr. Chair, and thank you very much, Mr. Ambassador, for your testimony and for investing your time here. We're grateful for your commendation, too, to the Government of Canada for its participation with the United States in trying to put as much pressure as we can on North Korea so they will capitulate in this terrible, tragic tradition of human rights violations to a degree. When you're talking about putting hooks in people, there's not much more that we've heard more severe here.
We had our own foreign affairs people brief us just recently on the dimension of the sanctions. This is a very broad question. We've seen sanctions make a substantial difference; although nothing has changed in the regime in this case, in a relatively short period of time compared to North Korea, sanctions have really made a severe impact on Iran.
We haven't seen any results, really, in these North Korean sanctions. They have done substantial damage to their economy, but we haven't seen any capitulation so far on their behalf.
Is there a reason these sanctions aren't working?
