Aleksandr Solzhenitsyn said this quote
“ Where an open war is impossible, oppression can continue quietly behind the scenes. Terrorism. Guerrilla warfare, violence, prisons, concentration camps. I ask you: Is this peace?The true antipode of peace is violence. And those who want peace in the world should remove not only war from the world but also violence. If there is no open war but there is still violence, that is not peace. ”
