A busted summit is the risk you run when too much faith is placed in personal relations with a leader like Kim, when the summit is inadequately prepared, and when the president had signaled he was confident of success." Trump was poorly received for his stance on the Warmbier incident. His supportive remarks for Kim Jong-un in his speeches while negotiating denuclearization were not received well by the Warmbier family, who were grateful to him after their son's return.
