A lot of countries have done horrible things to their neighbors or even to their own citizens. If every country that had bad leaders and did horrible things was “erased from the earth” there would not be much left.
Italy comes to mind. I was somewhat shocked when I first learned the true history of Rome and how it started out as a small regional domain and then century after century just kept invading and warring on their neighbors and then neighbor’s neighbors add nauseum. My first thought was how evil, all that killing and mayhem without cause.
