How do you deal with extreme force without using force in return? Peace activist Scilla Elworthy delivers a wise and impactful Tedx Talk about how to deal with playground bullies as well as dictatorial violence. Citing leaders like Nelson Mandela and Aung San Suu Kyi, she clearly maps out why and how nonviolence works. Political, physical, mental, emotional violence have their roots in fear and anger. Harnessing this fear and anger and using cooperation can deliver peace, and this talk from 2012 could not be more relevant today.
