Shulamit Ron, Demonstrator: “We hope the world hears us: the people of Israel are not the government of Israel. We don’t agree with the policy; we don’t agree with the way they behave; and we want to have a different future.”
Roi Tzohar, Demonstrator: “The Israeli people are hostages to their right-wing government. The people of Gaza are hostages to Hamas. And, basically, there has to be a way to overcome that and to stop the fighting and the killing. This [demonstration?] is to give everybody hope.”
