Japan's recent administration has been pushing for expanded military capabilities in East Asia under the banner of 'proactive pacifism'. This development is rather troubling with the US, UK, and Australia attempting to utilize Japan as a proxy to keep Chinese powers in check.
The last time this type of support of Japan's military was accepted was prior to World War 2 under the auspices of enabling Japan in pursuit of its own 'Monroe Doctrine' and ultimately led to the confrontation with the rest of the world.
