SEOUL, South Korea – After 14 years of painstaking labor, North Korea finally has a rocket that can put a satellite in orbit. But that doesn't mean the reclusive country is close to having an intercontinental ballistic missile.

Experts say Pyongyang is years from even having a shot at developing reliable missiles that could bombard the American mainland and other distant targets, though it did gain attention and the outrage of world leaders Wednesday with its first successful launch of a three-stage, long-range rocket.

A missile program is built on decades of systematic, intricate testing, something extremely difficult for economically struggling Pyongyang, which faces guaranteed sanctions and world disapproval each time it stages an expensive launch. North Korea will need larger and more dependable missiles, and more advanced nuclear weapons, to threaten U.S. shores, though it already poses a threat to its neighbors.
