A Korea-Japan Nuclear Weapon Free Zone has implications for the US assurance of extended nuclear deterrence to Japan and Korea. At the very least a nuclear weapon free zone would require the United States to commit to not firing nuclear weapons out of the NWFZ. A nuclear weapon free zone in North-East Asia could shift the focus of US deterrence away from nuclear weapons and towards the reliance on the conventional forces already deployed in the region.
