South Korea developing its own nuclear weapons, a topic long relegated to fringe advocacy, is now being discussed openly, including by its president. There are growing demands from the South Korean populace, the conservative media, and the ruling party for greater nuclear autonomy from Washington, redeployment of U.S. tactical nuclear weapons that were removed in the 1990s, or a nuclear-sharing arrangement with Washington similar to the arrangements that some North Atlantic Treaty Organization (NATO) allies have.
