When asked about the administration’s current position on removing US troops from the Korean Peninsula, a source close to the White House told CNN that it is viewed as something that could possibly happen in the future but “not until long after the nukes are verifiably gone.”

“That is the position,” the source said. A peace treaty signifies an agreement to establish legal and systematic policies for the whole Korean peninsula,” the official said, referencing the pledge made by South Korean President Moon Jae-in and Kim to bring a formal end to the Korean War, 65 years after hostilities ceased.
At 23:30 local time, North Korea changes its time zone to match South Korea (UTC+09:00) – a "first practical" impetus for Korean reunification, says the official North Korean agency KCNA.
