The global fight for gender equality wasn't a resounding success before the pandemic hit, but progress was being made. In many corners of the world, however, COVID-19 turned back that clock significantly. Violence against women—especially in the home—has been skyrocketing over the past year, says Phumzile Mlambo-Ngcuka, Executive Director of UN Women and the UN's top advocate for gender equality. And the toll on girls has been just as severe, says Mlambo-Ngcuka, with the UN estimating that as many as 11 million girls who left school during the pandemic will never return. At the same time, it has been women who have shepherded the world through the worst pandemic, as they occupy the majority of frontline healthcare jobs. Mlambo-Ngcuka joins Ian Bremmer on GZERO World.
