Walks away from Hanoi summit with Kim Jong Un, no deal

At the end of his second summit with Kim Jong Un in Hanoi, Trump abruptly cancelled a planned signing ceremony and told reporters he had "to walk" because North Korea wanted all sanctions lifted in exchange for dismantling only the Yongbyon nuclear site. The high-profile collapse left talks without any agreement, undercutting claims of breakthrough diplomacy while Trump downplayed the failure and praised his "great relationship" with Kim.
