As for the article, I'll wait for the action. Trump is so unreliable it's better to just ignore everything he says. If we are now willing to help UA fight for victory I expect Congress to stop chickenfeeding the weapons and start dumping them wholesale. If there aren't enough, increase production or stop sending them elsewhere.
Australia's government have a style guide with the example of "Anzac".

But for proper nouns, they distinguish "acronyms" (like Nasa) from "intialisms" (like FBI). An acronym is pronounced like a word, so they treat that word as a proper noun (capital first letter, others lower case).
That can be informative about pronunciation. The BBC writes the World Health Organization as WHO, not Who.
