You’re comparing linear distance to surface area of the south China sea. I’d be curious to know how close to Chinese airspace this bomber or group was flying. Fair enough though, if you think it’s not analagous we could open it up to the entire gulf of Mexico/Caribbean. It seems pretty clear to me that Chinese aircraft in that area would result in a tantrum that would probably escallate beyond tailgating.
Just looked it up, looks like it’s still Amazon. Could be missing something though.
