In a significant policy shift, former President Trump has announced that South Korea is now permitted to develop nuclear-powered submarines within the United States, specifically in Philadelphia shipyards. This decision is part of a broader initiative to bolster defense cooperation between the U.S. and South Korea amidst rising tensions in the region. Trump also stated that the U.S. will provide sensitive technology to facilitate this program, which includes a substantial investment from South Korea aimed at enhancing trade relations. South Korean officials have expressed optimism about this development, as it aligns with their national defense strategy against potential threats from neighboring countries.
