That's when and where U.S. President Donald Trump will meet North Korean leader in what will be the first-ever U.S.
In the case of the summit, many North Koreans believe it's been brought about in the first place by their country's hard-won success in developing a nuclear arsenal, made possible in part by their many sacrifices.
"We would like to express our deep appreciation to the United States government, President Trump, Secretary Pompeo, and the people of the United States for bringing us home", the men said.

President Trump faces a hard task persuading Mr Kim to abandon nuclear weapons and ballistic missile tests that heightened US-North Korean tensions throughout 2017.

Paxton pumped three straight fastballs - all strikes - to Teoscar Hernandez - 97 mph, 96 mph and 97 mph for a strikeout swinging. The only other Canadian to do so was Dick Fowler of the Philadelphia Athletics, all the way back in 1945.
Trump's tweet confirming the details of the visit came just hours after he welcomed Pompeo and three U.S. citizens who had been held prisoner by North Korea back to American soil from Pyongyang. "They regard the North Korea-US summit as an opportunity to confirm their status as a nuclear power".
The summit, which has been in the works since Trump accepted Kim's invitation to meet in March, will be the first ever meeting between a sitting United States president and North Korean leader.
Moon is scheduled to meet with Trump at the White House on May 22 to coordinate the allies' positions ahead of the U.S.
South Korean officials have also been involved in talks about the meetings.
"Clearly, credit goes to President Trump", Kang told CNN's Christiane Amanpour.
Mr Trump's own preference for the meeting was for the demilitarised zone between the two Koreas, but aides argued that this would look too much like Mr Trump going to Mr Kim's turf.
Seoul and Pyongyang have been technically at war since the 1950s because the conflict ended in a truce, not a peace treaty.
Abe is expected to ask Trump to push North Korean leader Kim Jong Un to address the long-standing issue of Japanese nationals abducted by North Korean agents in the 1970s and 1980s, the sources said.
