Sadeh says North Korean missile launch may encourage Star Wars concept North Korea's missile launch earlier this week and its promise of more to come rattled world stock markets and fueled an international backlash that could prompt renewed U.S. development of a space-based missile defense system. According to Eligar Sadeh (Space Studies) and a former aerospace engineer, the North Korean action represents a new complication in the global search for continued peaceful uses of space. In the space community, we were well aware that there had been space and missile technology transfer to North Korea, says Sadeh, a widely respected space policy expert and managing editor for Astropolitics: International Journal of Space Politics and Policy (a peer-review journal). A research associate with the Space Policy Institute at George Washington University, Sadeh has written extensively about the effects of militarization of space. The North Korean ballistic missile launch, though failed, raises concerns about rogue states, such as North Korea, that are not part of the international body of law; they operate outside the normally accepted norms of international behavior.
