"Both those on the East and those on the West should be clear with the fact that we are not moving away from our road that we beat the path for in '48. That is to say, that we have our own ways. We always bravely say what is right on this side and what is not, and what is right on the other side, and what is not. It should be clear to everyone that we cannot be an appendage to anybody's politics, that we have our own point of view and that we know the worth of what is right, and what is not right."- Josip Tito
