Australia and NZ are in a difficult position. From the day European’s arrived they have been aligned to the world’s dominant sea power. Both are remote and reliant on sea trade. I don’t know that we have the mental flexibility to change. More likely we will negotiate with the Whitehouse to get the best we can out of things under the circumstances. I wouldn’t expect major political parties here to publicly oppose Trump except on long established foreign policy like support of Ukraine. I wouldn’t mistake lack of protest with acceptance.

The countries with the most self-interest in securing our sea trade are China, Japan and South Korea for their food, energy and raw materials, not the USA. US is a net exporter to us but a lot of it is financial, services/IP and I think their commitment is somewhat less than it was post WW2.
