Korean Peninsula. With its powerful military, supported by high defense spending, a robust defense industry, and mandatory conscription, South Korea is capable of taking primary responsibility for deterring North Korea with critical but more limited U.S. support. South Korea also has the will to do so, given that it faces a direct and clear threat from North Korea. This shift in the balance of responsibility is consistent with America’s interest in updating U.S. force posture on the Korean Peninsula. In this way, we can ensure a stronger and more mutually beneficial alliance relationship that is better aligned with America’s defense priorities, thereby setting conditions for lasting peace.
