Destruction is not the answer!
Violence is unnecessary!
Violence only brings violence. Destruction is not always the solution. The destruction in Sherman's march was not necessary. They did not need to destroy everything.
Is like in autumn of 1914 when British aircraft from Dunkirk bombed Cologne, Düsseldorf, and Friedrichshafen, their main objective being the sheds of the German dirigible airships, or Zeppelins.
