Back when I still wore the uniform of a U.S. Army officer, and well before many of my former brothers in arms labeled me a traitor, I taught freshman (“plebe”) history at West Point. I loved asking my cadets provocative questions, the sort of queries they never heard in high school Advanced Placement U.S. history courses. Consider just one. At the end of the class on World War II, I always asked: “What is the moral difference between flying three planes into the Twin Towers and Pentagon—killing 3,000 civilians—and using hundreds of U.S. planes to firebomb Tokyo on March 9, 1945—killing some 90,000 civilians?” Suffice it to say that most cadets didn’t like this question at all.
Always Question Authority 
An excellent question! However, the response was expected & disappointing.
Remember Jung’s admonitions – We need more understanding of human nature because the only real danger that exists is man himself.
He is the danger and we are pitifully unaware of it. We know nothing of man, far too little.
This must be studied.
We are the origin of all coming evil!
