President Biden, in the somber tone and muted dress indicative of responding to tragedy, addressed the nation late last month. The Kabul airport attack had just claimed the lives of 13 American troops and over 60 Afghan civilians. He spoke movingly of the ultimate sacrifice made by our servicemen and -women. Then he turned his attention to our enemies. He said, "We will not forgive. We will not forget. We will hunt you down and make you pay."
