And as you just stated, both were liberated by people who used...wait for it...guns. I imagine what David would do differently is acquire guns and fight.
Both sides were likely facing a much, much larger force than they themselves had. Their forces may not have been trained to the level required to put forth the best defense, but the fact still remains, whether it's to defend your home, or free it from occupation, what you are going to need are firearms. Firearms, training, and sacrifice.
Sad and tragic, yet also expected, that you haven't learned that after all this time.
