Ali

Things start costing more.

And then it becomes hard to get what you need.

Research published last year at the Lancet Global Health Journal found that over the past decade, U.S.

and EU sanctions have caused more than half a million deaths per year.

And Ivo Leila says when you impose sanctions on a regime that's not responsive to pressure from its people, which has often been the case in Iran, it's an even more likely path to violence.

Ali says the Iranian people need help from other countries.

Help, he says, was promised.

Like Ali was chanting with his friends in the streets, they want this uprising against the Islamic Republic to be the last one.

Thank you to Narges Bajagli, co-author on a great book about the effects of sanctions on Iran, and to Eddie Fishman, author of Chokepoint's American Power in the Age of Economic Warfare.

I'm Mary Childs.
