My high school history teacher taught me that "if you ignore your past mistakes, you're bound to repeat them." He had us play the game Mastermind in class a few times to illustrate the idea that if we pay attention to our past mistakes and didn't repeat them, we would better come up with a solution.
He taught us that in the context of US history. Over the years I've held onto the incredible wisdom from my US history teacher. And I see, on the world front, that the US continues to repeat its past mistakes, thinking that the outcome will be different. I also see that other nations are seeing the mistakes the US is making and repeating the same, ancient mistakes of their own and the current mistakes of the US. I also see many other angry people repeating the same kinds of mistakes. And I see that lots and lots of people are dying and suffering
And I see that none of us are any closer to a solution.
