Both President Donald J. Trump and Secretary of State Pompeo made it clear once again that North Korea must agree too fully denuclearize.

During a joint appearance with the Japanese prime minister, Trump said if Kim does not “denuke,” sanctions will stay in place.

Trump also said he is ready to walk away:

All I can say is I am totally prepared to walk away. I did it once before. You have to be able to walk away. I am totally prepared to walk. It could happen, maybe it won’t be necessary. I hope it won’t be necessary to walk, because I really believe that Kim Jong-un wants to do something that is going to be great for his people and also great for his family and great for himself.

Reuters reports that Pompeo “reemphasized Washington’s stance going into the talks,” saying Trump “will reject anything short of ‘complete, verifiable and irreversible denuclearization of the Korean Peninsula.’” Pompeo also said Trump “is prepared to ensure a DPRK free of its weapons of mass destruction is also a secure North Korea.”

According to Axios, Pompeo said Kim “indicated to me personally that he’s prepared to denuclearize, that he understands that the current model doesn’t work.”

During the same joint appearance President Trump said this will take more than one meeting,”I don’t think it will be in one meeting. I think it will take longer than that. This has been going on for many, many decades.”

President Trump appears wiling to give the North Korean dictator a little more room than Security Adviser John Bolton, who in April suggested that President Donald J. Trump would not meet with Kim Jong Un until the North Korean dictator “agrees to give up his country’s entire nuclear weapons program”
