According to NBC:

U.S. intelligence agencies believe that North Korea has increased its production of fuel for nuclear weapons at multiple secret sites in recent months — and that Kim Jong Un may try to hide those facilities as he seeks more concessions in nuclear talks with the Trump administration, U.S. officials told NBC News…

Joel Wit, who negotiated a 1994 nuclear agreement with North Korea, said the U.S. always believed North Korea had two facilities to enrich nuclear material: Yongbyon and a second site the U.S. is aware of but whose name has not been disclosed…

The latest U.S. intelligence assessment concludes that there is more than one secret site, officials tell NBC News. The question is whether Kim will be willing to admit it.

This is the kind of deal that would work. We know North Korea would like to feel safe from U.S. attack. We can offer them that, along with eventual normal diplomatic and economic ties, in exchange for giving up their nuclear program. Giving up their nuclear program means first they have to declare everything they have, then let weapons inspectors in without restrictions to verify that what they said is true. Once they meet those commitments, the long process of dismantling and removing the materials and equipment can begin. Each time they fulfill a commitment, they can get something in return. This process was working pretty well in Iraq until George W. Bush messed it up. It was starting to work in Iran until Trump messed it up. Now Trump has been duped into a non-deal with North Korea when the Iran deal he was against is actually the kind of thing that could work with North Korea.

I don’t like the U.S. leadership looking stupid, ignorant and incompetent, but let’s face it, at this point that ship has sailed. The biggest risk here is actually that Trump will realize he was duped and overreact by doubling down on his earlier threats. North Korea would probably respond with threats of their own against the U.S. and its Asian allies. In the worst case it could escalate to one side or the other launching some kind of limited attack, followed by a larger retaliation, followed by regional alliances being triggered, and then the downward spiral to 2018 looking more like 1918. Let’s hope this is just my imagination getting away from me.
