Many people were shocked last week by news of the planned talks between the leaders of the United States and North Korea. U.S. President Donald Trump and North Korean leader Kim Jong Un are supposed to meet by May. Yet as of Monday, the Associated Press noted that North Korean media had yet to confirm the meeting. A South Korean spokesman said, “I feel they're approaching this matter with caution and they need time to organize their stance.” Observers say the meeting has raised expectations of progress in resolving the nuclear crisis on the Korean peninsula. But they warn the process leading to removal of all nuclear weapons from the area is complex. On Saturday, Trump said his talks with Kim could end with no agreement or they could be “the greatest deal for the world.”
