I said nothing about war, I'm talking about the COVID response in both cases.
The US Federal Government has spent trillions on COVID related bills. Over $5.3 trillion if this[1] is to be believed.
USD$5.3 trillion / US Population = $16k/person (approx)
AUD$291 billion / AU Population = AUD$11400/person (~USD$8,300 approx)
On the face of it, we spent a whole lot less, and have had at least as good, if not a better economic outcome.
