Comments on David Lang "The not-quite-quadrilateral: Australia, Japan and India", 21/07/2015
If the so called "not quite quadrilateral" are as that as the author described, it is unlikely to end up nicely.
For one thing, Australia may even have difficulties to decide in terms its relationships with China and the USA with the latter as its closest military ally and the former as by far its largest export market.
I would suggest the author compare who are more important to Australia, is that Japan and India, or the US?
Then it is not too difficult to see the futility of the attempt of so called "not quite quadrilateral" in containing China. It simply does not work.
