The long history of secret cooperation between Iran and North Korea in violation of international law stretches back for decades. North Korea first sold Iran ballistic missiles during the 1980s during Iran's war with Iraq. By the end of the 1980s, North Korea and China were supplying Iran with about 70 percent of its arms. Move to the 1990s, and Iran and North Korea had moved onto working together to develop long-range ballistic missiles. By the beginning of the 2000s, the Iranians were giving North Korea sensitive data from their own missile tests to improve the North Korean missile systems. This history of very close cooperation on ballistic missiles only has the potential to grow and deepen as a result of the Iranian nuclear deal. There is a growing evidence that Iran and North Korea have not only been cooperating on missile programs but also in the nuclear field. The media reports, as far as back as 1993, that there are indications that the Iranians financed North Korea's nuclear program with $500 million in return for nuclear technology. The strong relationship between Iran and North Korea was forged in secrecy. We do not even know the full extent of their working together. What we do know is that now that the world has given the Iranian nuclear program an apparent stamp of approval, North Korea has a lot to gain from the Iranians as well.
