How did Trump's relationship with North Korea evolve during his presidency?

Donald Trump's presidency saw a tumultuous relationship between the United States and North Korea. Trump started his presidency with a series of inflammatory tweets directed at North Korea and its leader, Kim Jong-un. These tweets escalated tensions between the two countries, leading to fears of a potential nuclear conflict. However, in 2018, Trump shifted his tone and began engaging in diplomatic talks with North Korea.

In June 2018, Trump and Kim Jong-un held a historic summit in Singapore, where they signed a joint statement pledging to work towards complete denuclearization of the Korean Peninsula. Despite this initial optimism, subsequent talks between the two countries stalled, and North Korea continued to conduct missile tests.

In 2019, Trump became the first sitting U.S. president to step foot in North Korea when he met with Kim Jong-un at the Demilitarized Zone. However, negotiations still failed to yield any significant progress towards denuclearization. In 2020, North Korea again began conducting missile tests, and the relationship between the two countries remained strained.

In the final days of his presidency, Trump continued to express his desire to continue diplomatic talks with North Korea. However, his term ended before any significant progress was made towards resolving the ongoing tensions.
