The diplomacy between the United States and North Korea -- which saw the former "delist" the latter as a state sponsor of terror in exchange for stronger assurances that Pyongyang was halting its nuclear program -- has already resulted in increased access for the UN's nuclear watchdog, the International Atomic Energy Agency. From State Department spokesman Sean McCormack:

"I understand that the IAEA has resumed its work. It has started to reapply seals," he told reporters.

"I think, as simply put, the North Koreans have started the reversal of their reversal, so they're getting back to that baseline where they were very close to meeting their obligations under the second phase that we're in, in terms of disablement" of North Korea's nuclear complex, he said.

Just to be clear, a "reversal of [a] reversal" is a very good thing when it means dismantling, instead of developing, nuclear weapons.
