"Never again," in my opinion are empty words. We have had leaders who have had the opportunity to stop our enemies yet they have opted for the more globally popular approach of not offending, not starting up with, not coming under the criticism of, etc. "Never again" must be spoken in words that our enemies understand: preemptive defensive action, an approach that shows that we truly care about our fellow Jews wherever they may live. Would we let guns point at our own children and not disarm (at the very least) the threat???
