The explosive yield of the nuclear device detonated last week by North Korea is estimated to be 2 1/2 times more powerful than the force of the nation’s last blast in 2009, scientists say. In announcing the Feb. 12 test, Pyongyang claimed the successful detonation of a “miniaturized device.”
Assuming North Korea is telling the truth, the use of a smaller device coupled with a bigger yield suggests the country is seriously advancing its ability to make viable nuclear warheads that could be fitted to a ballistic missile. (Global Security Newswire, Posted 20 Feb 13)
