I'm not mentioning any names because these guys are something.
Throughout history, we have seen that tyrants get things done at the beginning, but they begin to believe their own dog food, and go off the deep end. Nevertheless, people still believe in these guys.
No use naming all of them because we know who they are. If they were a stock, you would short them when they are at their peak. We have the saying that those who don't read history, are doomed to repeat it. I've always amended it to say 'We are always doomed to repeat history.' Who learns anything these days?
