Why is North Korea forging ahead with a nuclear programme?
Its leadership says it’s a necessary self-defence measure against a potential attack by arch enemy the United States.
It’s
the country’s first hydrogen-bomb test and considered by analysts as an
unanticipated advance in its limited nuclear arsenal.
How does a hydrogen bomb differ from an atomic bomb?
Atomic
bombs rely on fission, or atom-splitting, just as nuclear power plants
do. The hydrogen bomb, also called the thermonuclear bomb, uses fusion,
or atomic nuclei coming together, to produce explosive energy.
What would a successful H-bomb test mean to North Korea?
It
would be a big advance in the country’s nuclear weapons programme.
North Korea is thought to have a handful of rudimentary nuclear bombs
and has spent decades trying to perfect a warhead small enough to place
on a missile that can reach the US.

Why is there scepticism about the North Korean H-bomb test claims?
South
Korea’s spy agency thinks the estimated explosive yield from the blast
was much smaller than what even a failed hydrogen bomb detonation would
produce. The White House says early analysis of underground activity “is
not consistent” with the North’s claim of a successful H-bomb test.
Some
analysts say the North probably hasn’t achieved the technology needed
to make a miniaturised warhead that could fit on a long-range missile
capable of hitting the US.
What would a confirmed test mean to the region?
It
would further worsen already abysmal relations between Pyongyang and
neighbouring countries including South Korea, Japan and sour links with
ally China. It’s also expected to lead to a strong push for tougher
sanctions by the United Nations against the already impoverished nation.
