It must be nice to still be attractive to 99% of the people in the world; “that used to be us”.
Well, what the Aussies are essentially doing is recruiting mercenaries with the promise of citizenship. Not such a problem here because the people they’re recruiting are culturally very similar (Us, Canada, UK, etc.). Not such a great idea when, like the late Western Romans, you recruit foreigners who are very culturally different from you. That’s why our own program of handing out citizenship to Latin Americans and others who join the Army isn’t such a great idea.
