No one yet knows what deals U.S. President Donald Trump may have struck with Russian President Vladimir Putin during their private two-hour meeting in Helsinki. But it is already clear that Trump's self-congratulations for striking a deal to "denuclearize" the Korean Peninsula during his Singapore summit with Kim Jong Un are ringing hollow. In addition to backsliding in its working-level negotiations with the United States, the Kim regime has continued to solidify its position as a nuclear-weapons state. The master of the Kremlin is sure to have taken note of this.

North Korea specialists have long been skeptical that Kim would ever give up his nuclear arsenal, and recent evidence supports their judgment. Reports citing U.S. intelligence officials indicate that the North is pressing ahead with its nuclear weapons program, by ramping up missile and enriched-uranium production and concealing the size of its nuclear inventory.

Anyone who has followed affairs on the Korean Peninsula has seen this movie before. After all, Kim's father and grandfather wrote the script decades ago. Since the 1970s, the Kim regime has repeatedly expressed its desire for a nuclear-free Korean Peninsula, signed nonproliferation agreements and negotiated with the U.S. and South Korea — all while pursuing its nuclear weapons program. In this latest rerun, Kim has even reused his father's special effects. In May, he blew up a nuclear test site with the same cinematic flair that Kim Jong Il displayed when he dynamited a nuclear reactor's cooling tower 10 years ago.
