North Korean leader Kim Jong Un has taken steps to bolster the country's nuclear capability, inspecting a facility that produces nuclear materials. State media coverage indicates this move is part of a strategy to exert pressure on the U.S. following President Trump's inauguration. The recent visit highlights Pyongyang's intent to expand its nuclear arsenal, coinciding with missile tests and ongoing military tensions with the U.S. and South Korea, which North Korea views as invasion preparations. As diplomatic prospects remain uncertain, analysts suggest Kim may seek to leverage his enhanced bargaining power in future negotiations.
