US President Donald Trump predicted Saturday that he would know within a minute of meeting Kim Jong Un whether his "one-time shot" at peace with the North Korean leader had a chance of succeeding. The North Korean leadership, including Vice Minister of Foreign Affairs Choe Son Hui has also taunted Washington, calling Vice President Mike Pence a "political dummy".
Mr Trump's comments, made shortly before his departure for Singapore, underline his recent efforts to curb expectations for the summit, the first between a sitting United States president and a North Korean leader.
But the value of the event - long sought by the North, and which Trump apparently impulsively agreed to in March, reportedly without consulting his advisers - has been called into question by many seasoned experts.
North Korean leader Kim Jong Un arrived in Singapore just before 3 p.m. local time ahead of a much-anticipated summit with President Donald Trump on Tuesday.
The two are due to meet on Tuesday on the resort island of Sentosa for their high-stakes summit, the first-ever talks between the USA and North Korean leader and the culmination of a head-spinning diplomatic dance.
The fighting ended on July 27, 1953, but the war technically continues today because instead of a difficult-to-negotiate peace treaty, military officers for the US-led United Nations, North Korea and China signed an armistice that halted the fighting.

Authorities imposed tight security around the summit venue and the luxury hotels where the leaders were to stay - including installing extra pot plants outside Kim's accommodation to obstruct reporters' views.More news: Activists, students and volunteers mark World Environment Day
Trump and Kim will start their historic summit with a one-on-one session with translators.
Massachusetts Sen. Ed Markey, the ranking Democrat on the Senate Foreign Relations' subcommittee dealing with North Korea policy, said on "Face the Nation" Sunday that there's a "vast gulf" between the USA and North Korea's definition of what "denuclearization" actually means.
Kim arrived at Singapore's Changi Airport and was also greeted by Balakrishnan.
"Prime Minister Lee and Chairman Kim discussed Singapore-DPRK relations, developments in the DPRK and regional developments, including the recent positive developments on the Korean Peninsula", the statement reads.
Trump flew into Singapore's Paya Lebar Air Base aboard Air Force One, looking to lay the groundwork for a nuclear deal with one of America's most bitter long-time foes, directly following his divisive meeting in Canada with some of Washington's closest allies that further strained global trade ties. It's a reflection of the intense global curiosity over Kim's sudden turn to diplomacy in recent months after a slew of North Korean nuclear and missile tests a year ago raised serious fears of war.
It will be the first ever meeting between a sitting US President and North Korean leader.
He will have a bilateral meeting with Mr Trump on Monday.
