But he has since lowered expectations, backing away from an original demand for North Korea's swift denuclearisation.
The world is crossing its fingers.
The standard thinking goes that he needs quick help to stabilize and then rebuild an economy that has suffered amid a decades-long pursuit of nuclear bombs, and that the North Koreans see a unique chance to win concessions, legitimacy and protection from a meeting with a highly unconventional USA president who's willing to consider options past American leaders would not. An invitation to visit Trump in October, coupled with a few interactions with the UN General Assembly could be most catalytic.
The North has faced diplomatic and economic sanctions as it has advanced development of its nuclear and ballistic missile programs.
But does Kim simply want to play Trump for sanctions relief?
Last year it carried out by far its most powerful nuclear test to date and launched missiles capable of reaching the US mainland, sending tensions soaring to a level unseen in years as a newly-elected Trump traded threats of war and colorful personal insults with Kim, with Trump dubbed a "dotard" and Kim "Little Rocket Man". It will certainly be an exciting day and I know that Kim Jong-un will work very hard to do something that has rarely been done before ... "But they just stopped right before they crossed that line".

Ruled for seven decades by the Kim family, North Korea has been a murderous dictatorship since its inception.
Whether they could agree to a draft document will likely determine whether Kim and Trump can sign a tangible "outcome" at the summit.
Asked about a North Korean state media report that Trump and Kim were set to talk denuclearization and peace on the Korean peninsula, the official said the report is a hopeful indication.
Fifth, photo opportunities must be encouraged, not dismissed.
"Prime Minister Lee complimented the bold and admirable decision by Chairman Kim and President of the United States Donald Trump to come together for this Summit".
