The idea they would fake a nuke test frankly is preposterous.
Not even Kim would stoop to that.
If they say they did it, they did it.

Not really. It's not like outrageous claims and outright lies don't already occur in NK and other communist countries. In this case, howver, I do believe they were able to conduct a test on a device similar to what we made in the in the 1940s.
