north korea showed an interest in developing nuclear weapons since the 1950s. the nuclear program can be traced back to about 1962, when north korea committed itself to what it called "all-fortressization", which was the beginning of the hyper-militarized north korea of today. in 1963, north korea asked the soviet union for help in developing nuclear weapons, but was refused. the soviet union agreed to help north korea develop a peaceful nuclear energy program, including the training of nuclear scientists. later, china, after its nuclear tests, similarly rejected north korean requests for help with developing nuclear weapons.
