"Everybody knows what this regime is capable of doing, including people who favour Assad. And everybody knows what's happening in Syrian jails. Of course the regime denies all these charges. But do you remember the photographs by Caesar who took pictures of torture victims in a military hospital and then smuggled them out of the country? After he published them in 2013, many Syrians looked through them in order to identify missing family members and friends. I discovered a good friend. He was arrested one and a half years beforehand and then tortured to death. Western countries look at the Syrian civil war and say: "If we have to choose the lesser of two evils, we'd rather live with Assad.""
