How Powerful Is N.Korea's Nuclear Bomb?
North Korea's latest nuclear test was estimated to equal 6 or 7 kilotons of TNT, which makes it neither a failure nor a resounding success, according to experts.
"There is no such thing as a failed nuclear test," said Kim Tae-woo, former head of the Korea Institute for National Unification. "Even if there was no nuclear blast, scientists can gather data on what went wrong, and this is how the North has been able to continue developing nuclear weapons."
