Possibly the most important point of all, yes.<quoted text>
Quite right. The USA military budget is unsustainable and the US cannot afford an arms race with China.
They want all allies to share their Imperialist policies. IE they want to reap the benefits of being the reserve world currency in the oil dollars, but cannot possibly spend any more on the MIC.
In particular they cannot afford to let China, Japan and India buy oil from Iran in Euros or a basket of currencies.
They probably dont want Australia to trade their oil and gas with Asian Countries unless it is in US Dollars.
Politely say no. We dont mind supporting you in joint projects but unless the Australian Dollar is included in the Petro Dollars forget it.
