Among some U.S. officials, congressional aides, analysts and others who track North Korea, there was a sigh of relief Thursday as President Donald Trump headed home from Vietnam empty-handed from his talks with North Korean leader Kim Jong Un.

Trump said he walked away from a deal because of Kim¡¯s demands to lift all U.S.-led sanctions on North Korea in return for the denuclearization of its Yongbyon atomic complex but not others that the United States knows about.

In contrast, North Korea¡¯s foreign minister said Pyongyang offered to dismantle Yongbyon in return for a partial lifting of sanctions as a step toward better relations between the nations, technically still at war because the 1950-53 Korean War ended in an armistice rather than a peace treaty.
