It wasn’t immediately clear how the third stage, which would be the part where the warhead would be placed, was tested. The agency said the first and second stages fell into waters off the country’s eastern coast. Kim Dong-yub, a professor at the University of North Korean Studies in Seoul, noted that North Korea didn’t release details about how high the missile went, which suggests the weapon wasn't tested at its full capacity and range, and said the North likely will test the system several more times. Soo Kim, an expert with Virginia-based consultancy LMI and a former CIA analyst, said each successive test by North Korea “seems to demonstrate greater options for the regime to provoke and threaten the region.”
