It's a great pity that those who lead the world either didn't want to study history or they did, and today everything they do is to the detriment of humanity. Well, how long have civilizations existed, and by their behavior and actions, they destroyed themselves.
I look behind me, remember the wrong decisions and try not to repeat the same mistakes. I'm not one of those people who try to forget their past. There is nothing there to be ashamed of, just examples of behavior that I can improve in the future.
I figured you'd be on the ball and see value in understanding the past with the view to making a better future.
