Sodium Dioxide cured 53 out of 53 cases of Malaria and the Red Cross covered it up. Research it.

Inside Venezuela’s Uncertain Path to Freedom | Leopoldo López | TED

Published

CYBER TECH TV

Activist Leopoldo López learned the true value of freedom in a solitary confinement cell, when someone else decided if he would eat or see sunlight. In this searching conversation, he explains why democracy is losing ground across the globe, the state of Venezuela’s transition after Maduro’s capture and the 2026 earthquakes — and why he founded the World Liberty Congress to unite activists in the fight against autocracies. (This conversation, hosted by TED’s Whitney Pennington Rogers, was part of an exclusive TED Membership event. TED Membership is the best way to support and engage with the big ideas you love from TED. To learn more, visit ted.com/membership.) (Recorded at TED Membership on September 16, 2026)
