North Korea saves on nuclear spending, uses home-grown tech

PanARMENIAN.Net - North Korea has developed a nuclear weapons program despite poverty and international sanctions, using home-grown technology and virtually free labor to cut costs, experts said, according to Reuters.

South Korean government analysis has put North Korea's nuclear spending at $1.1 billion to $3.2 billion overall, although experts say it is impossible to make an accurate calculation given the secrecy surrounding the program, and estimates vary widely.

However, the weapons that North Korea has tested thus far are comparatively small and based mostly on less sophisticated fission, or atomic bomb, technology.

The isolated North's claim that its fourth and most recent test, conducted last week, was of a more advanced and powerful hydrogen bomb has been widely doubted, although experts said it is possible Pyongyang took the intermediate step of boosting an atomic bomb with hydrogen isotopes.

A former South Korean official involved in nuclear diplomacy with North Korea told Reuters previously that it was likely the North's nuclear program was cutting corners on safety, further driving down costs.

North Korea was at the bottom of a 2011 list on nuclear arms spending by Global Zero, a group campaigning to rid the world of nuclear weapons.

The full cost of Pyongyang's program that year was estimated by the group at $700 million, making it the lowest spender among nuclear states, beneath Pakistan's estimated $2.2 billion, although the analysis was made before the North's two most recent nuclear tests.

By comparison, the United States spent $61.3 billion on nuclear weapons in 2011, according to the report.
