In his tweet, Mr Trump added that he would personally greet the detainees when they arrive at Andrews Air Force Base at 02:50 EDT (06:50GMT) on Thursday. Warmbier's death escalated U.S.

North Korea and South Korea have been separated since 1953 with very limited exchanges, cultural or otherwise. When asked by reporters how it felt to be home, one of the men answered through a translator, "It's like a dream; we are very, very happy".
Secretary of State Mike Pompeo retrieved the men during a trip to Pyongyang to finalize the details of the summit.
The report added that an "in-depth discussion" was held on "practical matters" and procedures for holding the North Korea-U.S. summit and that Kim "reached a satisfactory consensus" on the issues discussed with Pompeo. The decision to withdraw the United States from the hard-won multinational Joint Comprehensive Plan of Action "sends a critical message", the USA president said on Tuesday.
"Kim Jong Un is a lot like Trump because he's bold and engaging in personal diplomacy", Fields said.

During Pompeo's visit to North Korea, he promised Kim economic help from the U.S.to bolster his country's economy. He was accused of unspecified 'hostile acts.

Kim Dong Chul had been in custody since late 2015. Singapore has diplomatic ties with North Korea but suspended all trade with the country in November previous year as worldwide sanctions were tightened.

"So I hope this time is different", said Gardner.
In North Korea's bombastic rhetoric, "denuclearization" has, for years, been a byword for United States troop withdrawals from South Korea and an excuse for stalling.
While Trump's withdrawal from the Iran nuclear deal might be meant to show Kim Jong Un that the US president follows through with his threats, it may also reinforce fears that Washington's negotiations can not be taken seriously - and that Pyongyang still needs its nuclear deterrent to ensure its survival.
The president has hailed the thawing in relations as a diplomatic breakthrough and chalked it up to his hardline stand with Pyongyang. And it underscored how closely the fate of his foreign policy agenda is being tied to the North Korean negotiations.
Trump confirmed the Americans' release on Wednesday morning, saying the group was airborne. It could be that achieving its longtime goal of the two nations' leaders sitting down face-to-face was enough to satisfy Pyongyang.
