Japan needs to push its weapons development and acquisition to the MAX.
Make it so obviously mutually destructive that the Chinese will NEVER dare to accost Japan or the Ryu Ku Isands, which now are being targeted by Red China’s community organizing operatives working to turn the population into an anti-USA haven.
I would love to see South Korea , Taiwan,Japan, The Philippines, Australia and the USA enter into an updated alliance pact much like NATO.
I think you could probably add India to the list. China would find herself isolated rather quickly if she pushes too hard...
