Japan's embassy in China posted today: "The Japan-US Extended Deterrence Dialogue (EDD) was held in the United States on February 19. Both sides reiterated the United States' commitment to Japan's defense, using the full range of US capabilities, including nuclear capabilities, and discussed issues related to arms control, including Russia and China."
Comment: Japan's move is essentially a public embrace of the US nuclear umbrella, deeply tying itself into the US military confrontation system.
Under the banner of "extended deterrence," it brings in the US to talk about nuclear capabilities, deliberately bringing in China and Russia into the issue. Essentially, it is pushing for its own military relaxation, while at the same time stoking regional threats and creating an excuse to break the peace constitution and accelerate military buildup.
