Milley will be meeting China with a welcome wagon.
How come Japan and S. Korea are not part of this group
they have the most extensive militaries in the region.
They also have big economies that rely on shipping.
Japan and South Korea despise each other regardless of their mutual suspicion of China.
Also, Australia is a 5 eyes country, Japan and South Korea are not. Japan and South Korea are also strictly neutral when it comes to anything that doesn’t directly affect them.
