Tuesday’s landmark summit comes after 18 months of insults and threats between US President Donald Trump and North Korean leader Kim Jong-un.
Trump once referred to Kim as “rocket man”, who, in turn, has called him a “mentally deranged US dotard”.
The North Korean leader has in the past threatened to hit the US territory of Guam in the Pacific.
