Tokyo Expands Defense Industrial Base and Partnerships

Japan is rebuilding its security architecture around the concept of denial, aiming to deter attacks by making them too costly for potential aggressors. The government has announced a new state body to support private defense firms and has partnered with the US and Germany to enhance defense cooperation. The denial concept has three parts: expanded development and deployment of long-range missiles and drones, a stronger domestic defense industrial base, and wider cooperation with countries that oppose changing the status quo by force.
