Cats out of the bag now anyway. If NK wants to use another bomb and really cause a panic with one that actually works as designed, then I say let them.
Now that its happened, it might as well benefit us since China won't back sanctions in practice, and Putin's busy assassinating critics of his Admin.
I think a nice big H-Bomb blast might sober up some of the undecided voters here in the US.
"I think a nice big H-Bomb blast "
Thats exactly what he is working toward. These aren't just nukes he's testing, they are plutonium cores, intended to initiate a fission device. Thus clown is saying "F" you to the entire world, China included. A 20KT device is not what he's after. IMHO
