Obama says North Korea will achieve nothing from rocket launch SEOUL (Reuters) - U.S. President Barack Obama said on Sunday that North Korea, which has planned a rocket launch for next month, will achieve nothing through threats and provocations. Obama, talking on the eve of a nuclear security summit in Seoul, said such a launch would increase reclusive North Korea's isolation. North Korea says the rocket will send a satellite into orbit.
