New Delhi, Jun 14 (ANI): The United States President Donald Trump declared that there is no longer a nuclear threat from North Korea as he returned to Washington after holding the historic summit with the reclusive nation's leader Kim Jong-un in Singapore on Wednesday. In a pair of tweets, Trump wrote, "Just landed - a long trip, but everybody can now feel much safer than the day I took office. There is no longer a Nuclear Threat from North Korea. Meeting with Kim Jong Un was an interesting and very positive experience. North Korea has great potential for the future!" "Before taking office people were assuming that we were going to War with North Korea. President Obama said that North Korea was our biggest and most dangerous problem. No longer - sleep well tonight!," he wrote in another tweet. His tweets came shortly after Air Force One landed at Joint Base Andrews just outside Washington. On Tuesday Kim and Trump had met for a maiden bilateral summit at Singapore in which they signed an agreement for a stable and peaceful Korean regime. The historic US-North Korean summit began with a handshake between two leaders as they went on to sit side by side and held an hour-long talk in the resort island of Sentosa. The two leaders also signed a post-summit joint declaration.
