Students once asked me, if being a historian, I could predict the future and I said "No, I can't. But, I can tell what you what won't happen.", and someone said "What won't happen? What do you know what won't happen?" and I gave two answers. I said "Russia will never allow the reunification of Germany" and "whites in South Africa will never give up their tyranny without a bloodbath." So, let's not take me as a prophet.
