How has North Korea changed its stance towards South Korea and what are its recent military actions?

North Korea has dramatically shifted its posture toward South Korea, with Kim Jong Un claiming constitutional changes giving him the 'legal right to annihilate South Korea.' In October, North Korea symbolically severed physical connections by destroying roads and rail links that had connected the two countries since the 2000s. Simultaneously, North Korea is conducting record numbers of ballistic missile tests while deepening military cooperation with Russia. This includes supplying millions of artillery shells to support Russia's war in Ukraine, with reports suggesting thousands of North Korean soldiers may be prepared for deployment there. This unprecedented military alliance could be facilitating the transfer of modern Russian military technology to North Korea's forces.
