This week, Australia learned that old geopolitical relationships and so-called ‘free trade’ treaties mean little when it comes to US policy. The obsequious way our political class fawns after the US has been a constant sickening element of our national identity for as long as I can recall. When I was a child, we were told by our Prime Minister that Australia was “all the way with LBJ”, a foreign policy that took out nation, against all reason, into the Vietnam War. Now, the US President is demonstrating why a reliance on the US as a ‘good citizen’ of the world is a poor strategy for an advanced nation to adopt. The other interesting aspect of what is going on is that the world is once again entering an experiment that will provide knowledge about the impacts of ripping up free trade agreements and increasing barriers to entry. Theorising is one thing but now we have a practical experiment underway. This is Part 1 of a series on the current debate about tariffs.
