The Australian nuclear submarine program will cost up to $368 BILLION - but judging by past military expenditure overruns, you can double that - which will give us three American-manufactured nuclear submarines, of which only ONE will ever be operational for active duty at any time.
I don't wear a starched white uniform with a gold shoulder braid - called "aiguillettes" and originally worn on a provost marshal's shoulder and used for hanging the condemned but, of course, you already knew that! - but even I can tell you that just ONE submarine wouldn't hold back the Chinese hordes should they ever decide to get their hands on all that iron ore or baby formula or quaffable red wine without paying for it.
Wouldn't it be better if we spent just a fraction of that $368 BILLION preparing our kids by teaching them Chinese instead of all those non-gender-specific pronouns? I've only just now got my head around LGBTQIA - which, by the way, is not an acronym (but AUKUS is) but an initialism; look it up! - and I know what those kids are going through.
You and I are too old to learn the Chinese language but at least you now have learned the difference between an acronym and an initialism!
