Analysis of Rajin Port indicates that North Korea has been steadily supplying weapons to Russia from August 2023, suggesting its munitions industry is operating as usual. Furthermore, sanctioned Russian cargo vessels are transporting containers from Rajin Port without impediment, demonstrating the ineffectiveness of international sanctions against both North Korea and Russia. In addition, the new Trump administration’s “America First” policy is weakening the existing international order and cooperative systems, exacerbating conflicts starting with trade wars. The international community will likely realign into smaller blocs based on national interests, with some nations pursuing independent survival strategies. This will accelerate an arms race, including nuclear weapons, increasing global instability.
