The U.S., South Korea and Japan held a military drill together and flew advanced warplanes for a joint exercise in a show of force against North Korea. The three countries staged an aerial drill over international waters off South Korea's southern Jeju island. The training also involves nuclear-capable B-52H bombers from the U.S., and is meant to improve the deterrence and response capabilities against North Korea's evolving nuclear and missile threats, according to South Korea's Defense Ministry. On the same day, top South Korean, U.S. and Japanese military officers urged North Korea to cease all unlawful activities that threaten regional security during a trilateral meeting in Seoul. The chair of the joint chiefs of staff from South Korea, the U.S. and Japan discussed North Korea's deployment of troops to Russia to support its war against Ukraine and Russia's potential transfer of military technology to North Korea in return.
