China basically told Australia to stfu. "If u make China enemy then China be enemy!" they said. Then they posted a buch of stuff about Australian SAS soldiers being overly brutal, which there appears to be some truth to but is unrelated. Then China tariffed or banned Aus goods. Then, you'd imagine, Australia realized it was fucking with a country which could wreck them tenways from Sunday and how much can we rely on the US Marines to bail our ass out do ya think?
Maybe I came from a lab. It would explain a lot.
