China Wants What Australia Has. By Niall Ferguson.
Niall Ferguson provides his perspective on the threat of China from an Australian viewpoint. He dispels the myth that China does not have imperialist intentions and argues that we are grossly unprepared for Chinese aggression, given our abundance of natural resources, sparse population, and close proximity to China.
Post stone-age Australia only exists by virtue of the British Navy up until 1941, and then the US Navy.
The great distance of Australia from likely hostile powers is also a crucial factor. But in an age of aircraft and missiles, that distance no longer offers as much protection.
