As a young Syrian-American, visiting Aleppo with my family was the highlight of my year. The sweet scent of jasmine abounded in the gardens, mixed with the aroma of Turkish coffee. At night, cafes were always full of people enjoying the cool breeze. But the city’s landscape has drastically changed: Barrel bombs have destroyed entire districts. Missiles have shattered homes, schools, cars, and lives. My family tells me that the pictures in the news do not do justice to the enormity of the devastation. Aleppo has been dubbed “the world’s most dangerous city.”

The Global Summit to End Sexual Violence in Conflict ended, for me, not with a bang but with a tiny symbol of my irrelevance. As I stood, furiously tweeting, after the summit’s closing plenary, I was literally pushed aside by a bodyguard to Angelina Jolie. (Special Envoy to the United Nations High Commissioner for Refugees Jolie was a co-host of the summit, with UK Foreign Secretary William Hague.)

I spent the past week in London at the Global Summit to End Sexual Violence in Conflict hosted by UK Foreign Secretary William Hague and UNHCR Special Envoy Angelina Jolie. It was a historic gathering of ministers and other government representatives, UN officials, the ICRC, and civil society, including our Campaign to Stop Rape & Gender Violence in Conflict.

Everyone keeps asking me if we need Angelina Jolie. Leading up to the Global Summit to End Sexual Violence in Conflict, which Jolie and UK Foreign Secretary William Hague are chairing in London this week, they want to know whether she is useful to this cause. I’ve been thinking a lot about this and have been searching for an answer. And I think I’ve found it.

The Central African Republic may have a new leader for now—Interim President Catherine Samba-Panza was sworn in in January—but there are still old problems that exist when it comes to the country’s long history of sexualized violence.

To combat sexualized violence, advocates and technologists have created new, tech-based apps and services in recent years. Some recent anti-rape device creations include rape-resistant underwear, female condoms with teeth, hairy leg tights, and even “killer tampons.” But not all of the creations are that bizarre. Some tech-based responses include smartphone apps, GPS tools, and other personal safety services and software that may be useful in the right—or wrong—situation.
