The Pentagon foresees a “more limited” role in deterring North Korea, with South Korea taking primary responsibility for the task, according to a policy document released on Friday, a move that could lead to a reduction of US forces on the Korean Peninsula.

South Korea hosts about 28,500 US troops in combined defense against North Korea’s military threat and Seoul has raised its defense budget by 7.5 percent for this year.

“South Korea is capable of taking primary responsibility for deterring North Korea with critical but more limited US support,” the Pentagon said in the 25-page National Defense Strategy document that guides its policies.

“This shift in the balance of responsibility is consistent with America’s interest in updating US force posture on the Korean Peninsula.”

In recent years, US officials have signaled a desire to make US forces in South Korea more flexible, to potentially operate outside the Korean Peninsula in response to a broader range of threats, such as in defending Taiwan and checking China’s growing military reach.
