Russia and North Korea agree to an alliance if either is attacked

Russia and North Korea have agreed to support one another in the event either is attacked. It's the strongest partnership formed between Moscow and Pyongyang since the collapse of the Soviet Union. This comes at a time when both nations face escalating tensions with the West. US officials express concern over the relationship, fearing Russia will help North Korea expand its nuclear weapons arsenal whilst North Korea helps keep the Russian army supplied with weapons for its war on Ukraine.
