In a radio interview on Friday, August 11, Prime Minister Malcolm Turnbull said: "If there’s an attack on the US, the ANZUS Treaty would be invoked and Australia would come to the aid of the United States, as America would come to our aid if we were attacked". He did add the proviso that "how that manifests itself obviously will depend on the circumstances and the consultations with our allies". Nonetheless, he doubled down that "the American alliance is the absolute bedrock of our national security" and "in terms of defence, we are joined at the hip".
I lived through the ANZUS crisis in New Zealand in the 1980s. I recall a droll cinema-style poster that proclaimed: "Coming to a theatre near you, starring Ronald Reagan and Margaret Thatcher, 'Apocalypse'. Thatcher promises to follow Reagan to the end of the world, and he promises to do his best to bring it about". Today it is Australia that seems to have locked itself into the support role to extinction.
