From our point of view from the other side of the Pacific, Americans tend to focus on the points of first resistance from the People's Republic of China - Taiwan, South China Sea, etc.
Is that really what China is worried about? Is she really building her huge Navy to challenge us somewhere west of Wake, or is she thinking of something else we are just too parochial to see?
As with most things, it is helpful to take a deep breath and ask yourself - what does the map say?
