Is anyone surprised? I'm not. The Nork's have been playing this game of lying and deceit to get what they want for a very long time.
Until the Nork's have a "Berlin Wall" type of moment such as where the North Korean people are allowed to freely leave the country, the North Korean Government starts feeding the people instead of starving them or our own military is welcomed in to supervise the true dismantling of their nuclear program AND the remains of our war dead are turned over respectfully there's just no way in hell the Nork's should get even a modicum of trust from our Government, period.
In short, Kim Jong Un shouldn't be trusted as far as he can be thrown, period.
Trump and Pompeo are just clueless and naive ...
