The newsies have been chattering about the North Korean nuclear test all day. Amid the torrent of words on both lefty NPR and righty Fox, the one important number has NOT been given. A further example of innumeracy among the newsies. They can't count, can't add, can't subtract.
The missing number is yield, in kilotons. The first two North Korean tests were fizzles. Their yield was so low (1 kiloton) as to tell us something went wrong and the bomb barely went off. Any decent sort of nuke ought to have a 20 kiloton or better yield.
Question for the world's newsies. Did this North Korean test yield enough to make us think they have it working right? A yield of 20 kilotons makes them a nuclear power. One kiloton makes them wannabes.
The chattering classes have taken the North Korean claim of "miniaturized" to mean the bomb is small enough to put on their ballistic missile. You can believe as much of that as you want to.
