I don't know that much about Chris Wallace, but I do remember a few things about Mike Wallace.
I remember one conversation Mike Wallace had on air with Peter Jennings, and they were talking about a hypothetical case where they could see from a vantage point American troops about to be ambushed by enemies.
Jennings first opined that he would warn the American troops if possible about the ambush.
Wallace proceeded to upbraid him for "betraying" journalistic principles.
According to Wallace, it was not the job of journalists to pick sides. He would not warn the American troops. Jennings finally relented and agreed with Wallace that is was far more important to see American troops slaughtered than betray journalist principles. Which apparently are the principles of knaves and skunks.
As if America was taken over by Nazis, Communists, or Jihadis, Wallace would be allowed to practice his "journalistic principles" and not be imprisoned or executed out of hand.
That statement made me loathe Wallace and others like him who deep down hate America and actually have no principles or morals.
