On Saturday morning, the United States and Israel commenced a joint military operation against Iran, marked by the death of Supreme Leader Ali Khamenei. This shocking news quickly spread worldwide, with Iran retaliating through missile strikes and closing the Strait of Hormuz. In Brazil, alongside closely following developments, many individuals turned to WhatsApp to process the implications of these events.

A monitoring study of over 100,000 public WhatsApp groups by Palver revealed that discussions about Iran, which previously constituted less than 1% of circulating messages, surged more than twentyfold on Saturday, with debates persisting into Sunday. Analysis of the messages unveiled three main narrative axes driving the conversations. The largest axis, which accounted for slightly more than half of the classified messages, originated from right-leaning users who framed the attack as part of a broader ideological struggle, linking Khamenei's death to geopolitical considerations and upcoming elections.

This surge in communication highlights the rapid sharing of information and the significant impact of international events on domestic discussions in Brazil. As Brazilians engaged in conversations about the implications of the conflict, it showcases the interconnectedness of global politics with local public sentiment, sparking debates on nationalism, geopolitical alliances, and the potential for conflict to influence national elections in Brazil and beyond.
