Data: CSIS Missile Threat, Axios; Chart: Jacque Schrag/Axios
North Korea tested yet another ballistic missile on Friday, launched a barrage of rockets near the border with South Korea, and flew warplanes so close to South Korean territory that Seoul scrambled jets of its own in response, South Korea's military says.
Why it matters: North Korea is testing missiles at an unprecedented rate this year. U.S. and South Korean officials are still awaiting a seventh nuclear test, which they believe could take place at any time.
