It is clear the US is now no longer part of the West under Trump.
As a response from Australia we could, and should, do the following:
Tariffs: We buy more of your $hit than you buy ours...you lose.
You threaten us with tariffs for holding your tech companies to moral and legal account. Reciprocate and start lifting tax on these companies.
Renege on the AUKUS nuclear submarine deal ($370B AUD), forfeit the $800 down payment, go back cap in hand to France (recoup the $5B our former PM forfeited). Get a better product earlier and GB can still be part of it.
Increase the cost of using our military facilities and naval bases. In fact you have never ever come to our rescue when needed, so maybe pi$$ off.
Etc
This won't end well for Trump and sadly the US ....
