People watch a television news screen showing pictures of US President Donald Trump (C) and North Korean leader Kim Jong-Un (R) at a railway station in Seoul on November 29, 2017.

“How does the U.S. administration manage a very complex negotiation with North Korea even as it is trying to manage a very complex renegotiation with Tehran and also the European Union?” Peterson said, adding that the administration faces a “bandwidth issue.”

“You talk about bandwidth, one of these foreign policy issues alone would be queuing up a lot,” Davis added. “But, my goodness, you have them all happening at the same time while you have the domestic stuff and you just have how much does he have to pay attention to any one issue.”

Trump said Tuesday that the time, date and place were chosen for his meeting with Kim, but he did not divulge any further details.

As it stands, North Korea remains the only nation to test nuclear weapons this century.

Since 2011, Kim has fired more than 90 missiles and conducted four nuclear weapons tests, which is more than what his father, Kim Jong Il, and grandfather, Kim Il Sung, launched over a period of 27 years.

The North’s arsenal includes short- and medium-range ballistic missiles, intercontinental ballistic missiles and cruise missiles. The Hwasong-15 intercontinental ballistic missile is the most powerful rocket the North has tested to date.

The missile, also known as KN-22 by the U.S., is believed to have a range capable of hitting the entire continental United States, according to estimates from the Missile Defense Project.

In short, Kim spent much of last year perfecting his arsenal by launching 24 missiles and carrying out North Korea’s largest nuclear test.
