The big picture: The imminent threats from North Korea seem a world away from June 2018, when Trump returned from his Singapore summit with Kim to boast, "There is no longer a nuclear threat from North Korea."
In reality, Kim has expanded his nuclear arsenal since then, analysts say.
Using data from analysts and governments around the world, Japan's Nagasaki University estimated in June that Kim now has as many as 30 nuclear warheads. That's on the lower end of estimates, and it's up from as many as 20 warheads in the same study last year.
"Even though they're not testing right now, they're operating at full tempo," said Victor Cha, the National Security Council director for Asia under President George W. Bush and Korea chair at the Center for Strategic and International Studies.
The Trump administration declined to comment.
Between the lines: Daniel Russel, President Obama's assistant secretary of state for East Asian and Pacific affairs, said that of the two leaders —Trump and Kim — only one appears to have had a strategy.
Trump broke with precedent, met twice with the isolated dictator and said "we fell in love" over "beautiful letters."
Russel described Trump's approach to Kim as "magical thinking, based on a narcissistic conviction that the tractor beam of Donald Trump's charisma was going to capture the Leninist dictator and pull him into some kind of condo-developing frenzy of good behavior."
Despite Trump's charm offensive, Kim's nuclear arsenal has only grown.
