One thing is for sure, the Norks are not worried about Obama’s reaction to their repeated provocations.

SEOUL, South Korea (AP) — North Korea has moved a missile with “considerable range” to its east coast, South Korea’s defense minister said Thursday, but he added that there are no signs that the North is preparing for a full-scale conflict.

The report came hours after North Korea’s military warned that it has been authorized to attack the U.S. using “smaller, lighter and diversified” nuclear weapons. It was the North’s latest war cry against America in recent weeks. The reference to smaller weapons could be a claim that North Korea has improved its nuclear technology, or a bluff.

The North is not believed to have mastered the technology needed to miniaturize nuclear bombs enough to mount them on long-range missiles.

South Korean Defense Minister Kim Kwan-jin said he did not know the reasons behind the North’s missile movement, and that it “could be for testing or drills.”
