Je partage avec vous une citation de Siegfried Hecker, un des rares experts nucleaires qui ont visite l'installation de Yongbyon:
"Can you rule out the possibility that it was a hydrogen bomb?
I find it highly unlikely that the North tested a real hydrogen fusion bomb,
but we know so little about North Korea’s nuclear weapons design and test results that
we cannot completely rule it out. A modern hydrogen bomb is a two-stage device that uses a fission bomb to drive the second stage fusion device. A two-stage device is very difficult to design and construct, and is likely still beyond the reach of North Korea today. However, by comparison,
China’s early nuclear weapon program progressed rapidly. It tested its first fission bomb in 1964 and
less than three years later demonstrated a hydrogen bomb—and that was 50 years ago. North Korea has now been in the nuclear testing business for almost 10 years, so we can’t rule anything out for certain."
