No sitting U.S. President has met with a North Korean leader in seventy years — so Trump’s meeting with Kim Jong-un is obviously a pretty big deal. This isn’t the first time North Korea has tried to have a meeting with the U.S. — in fact, they have been trying for decades. The difference is that no sitting president ever said yes before until Trump.
Not so long ago, Trump would constantly chide and taunt Kim on Twitter, to which the North Korean leader would respond with insults of his own. So, the fact that they went from exchanging blows to meeting at an unprecedented summit is interesting and definitely historic — but a historic move isn’t always a positive one.
North Korea has been treated like an international pariah for decades because it’s a shockingly authoritarian nation, with a leader who blatant disregards human rights. One South Korean think tank estimates that Kim Jong-un has executed 340 people, including 140 officials, in the five years he's been in charge — so the country is not exactly viewed positively by the rest of the world.
Kim is a brutal dictator in every sense of the word, and the fact that he sat down with a U.S. president is a huge propaganda victory for him — that can be spun to mean anything he chooses in North Korea. Trump claims that he’s trying to achieve what no president has before with the summit, but plenty of experts of skeptical about the summit’s benefits and outcome, considering that both leaders are notoriously hot-headed.
