Well sooner or later i guess more and more countries will be “forced” to build nuclear weapons because it looks like an easy way to protect yourself against a superior forreign millitary force. unfortunately countries like north korea,Iran... might think the same way.
You are quite correct. The idea that Australia can begin to compete militarily against China with conventional weaponry is just stupid.
The most expensive thing in the world is a second-best military: good, but not good enough to win.
