second-strike capability

China recently conducted a rare ballistic missile launch from a nuclear-powered submarine into the Pacific, which Beijing described as routine. This event has heightened concerns among regional powers like Australia, Japan, and the United States, who have raised issues regarding insufficient notification. The test is seen as a strategic signal to the US and its neighbors, particularly Japan, amidst ongoing discussions about China's military expansion and nuclear triad development. The incident underscores the fragility of global nuclear governance and is likely to prompt increased defense investment and security coordination among US allies in the region, reflecting current geopolitical tensions and the growing significance of China's strategic capabilities.
