How odd. It reads quite differently if you don't cherrypick and take out of context:
Not really. The location of North Korea didn’t suddenly occur, through the magic of plate tectonics. It’s quite believable. It’s like suddenly realizing KC is in the middle of the US and might just make a good, centralized distribution hub.
As far as testing goes, that’s meaningless in the overall picture of whether they’re a threat. The tweet from last June and this statement is BS. They have yet to provide a warhead count or inspection of a device.
Pakistan hasn’t tested a nuclear device, since the 80s. The neighboring country of India does not disregard them as a nuclear threat, based on that criteria. It would be absurd.
