North Korea claims it has tested an underwater nuclear attack drone capable of creating a “radioactive tsunami” to destroy enemy naval groups and operational ports. Analysts, however, have cast doubt on the regime’s claims, with some suggesting it could be an attempt at deception or a psychological operation. North Korean leader Kim Jong Un oversaw the tests, which come after the US and South Korea carried out their largest joint military drills in five years. Pyongyang views such exercises as rehearsals for invasion and has threatened “overwhelming” action in response.
