Australia is actually situated in an area of the world that is already a hotly contested resource zone. First there is Australia herself. She is chockful of strategic minerals such as iron ore, nickel, bauxite/aluminium, copper, gold, silver, uranium, diamond, opal, zinc, coal, oil shale, petroleum, and natural gas.
In her region Lie some of the most hotly contested sight of offshore oil, most of all the Spratly Island area.
Also the waters around her play host to the largest commercial transport and fishing fleets in the world. They are hotspots for pirates and drug dealers. And geographically Australia has been cursed with a huge and wild border area. Add to all this they have a history of conflict with the regions Totalitarian states.
Why else would they build the most remarkable system of radar , JORN, the world has ever seen?
So theres no question Australia needs a strong defense. And theres no question America needs her to. The question is do we go past the JSF and sell them the F-22? I myself say no.
The thing is the F-22 will "win wars". Thats why we built it and thats why so many want it. It is the most vital war winning system we have right now. It is that undefeatable. With the F-22 we are guaranteed to achieve air dominance and you saw what that did to the Iraqis in the Gulf Wars.
