" Enemies are always the same, or become so with time, for they could not be enemies otherwise. It is those who actually differ among themselves who pose the greatest danger. They long to meet one another, because their differences do not bother them. And they are the worst. We and our enemies will combine forces to fight those who allow us to differ from them and do not let this difference disturb their sleep; we will destroy them in one fell swoop from three sides... "
