Based on the title, I thought this was an article about The Kalinga War, a war so bloody it moved the Emperor Ashoka to embrace non-violence and spread Buddhism throughout Asia.
TFA points out that International Law (an output of moral reckoning, if you will) is being dismantled by those in power whose morals are lose.
I wonder, just how long is the memory of civilizations to remember the lessons + morals of the past & how many generations does it take for a civilization to unlearn the wrong lessons.
