@LanguageMan1 By "our country", I take it you mean the US?
If so, I'm assuming you're familiar with the fact that Australia has agreed to purchase a fleet of 8 nuclear submarines at a cost of around A$368 billion: https://www.theguardian.com/world/2023/mar/14/aukus-nuclear-submarines-australia-commits-substantial-funds-into-expanding-us-shipbuilding-capacity
That's a massive amount of public money.
And it's predicated on the fact that the US will supply the submarines as promised.
And that the purchase is predicated on an assumption that the US will take military action if an authoritarian state (China) attacks a liberal democracy (Taiwan).
And that the US will honour its commitments to another ally and liberal democracy (Australia).
Given Trump's proven unwillingness to back a liberal democracy (Ukraine) against an authoritarian state (Russia), support for Taiwan in the event of sn Invasion looks less likely.
That's a lot of uncertainty for a A$368 billion defence contract.
