President Barack Obama on Thursday warned that North Korea’s young leader is hell bent on developing a nuclear weapon , even as that country criticized his planned Friday visit to a site where the United States once dropped an atomic bomb.  

Obama called the mostly isolated country’s pursuit of a nuclear weapon a "big worry for all of us," even while saying U.S. officials believe “they’re not at a point right now that they can effectively hit U.S. targets.”
