We’re trying to sell peace, like a product, you know, and sell it like people sell soap or soft drinks. And it’s the only way to get people aware that peace is possible, and it isn’t just inevitable to have violence. Not just war — all forms of violence. People just accept it … [but] We’re all responsible for everything that goes on, you know, we’re all responsible for Biafra and Hitler and everything.
So we’re just saying “SELL PEACE” — anybody interested in peace just stick it in the window. It’s simple but it lets somebody else know that you want peace too, because you feel alone if you’re the only one thinking “wouldn’t it be nice if there was peace and nobody was getting killed.” So advertise yourself that you’re for peace if you believe in it.
