North Korean leader Kim Jong Un inspected a factory producing ballistic missile launch vehicles this week, where he demanded officials fix "flaws" in production to prepare for war with South Korea, according to state media on Wednesday.

The brief Korean Central News Agency (KCNA) report heavily focused on the roles of factories in facing off against the "main enemy" South Korea, but it did not name them or the weapons Kim inspected on Jan. 8, widely believed to be his birthday, and the following day.
