The American soldiers were brave, but courage is not enough. David did not kill Goliath just because he was brave. He looked up at Goliath and realized that if he fought Goliath’s way with a sword, Goliath would kill him. But if he picked up a rock and put it in his sling, he could hit Goliath in the head and knock Goliath down and kill him. David used his mind when he fought Goliath. So did we Vietnamese when we had to fight the Americans.
