Speak with caution. Even if someone forgives harsh words you've spoken, they may be too hurt to ever forget them. Don't leave a legacy of pain and regret of things you never should have said.
Our fight was not for ownership of a fertile piece of land. It was about defending the sanctity of ethics and fairness and dignity --- about defending humanity. Those are the values worth fighting for. If we forsake those very values in war, we become the very thing we are fighting against. We become them. Then what do we have left to fight for?
There's no room for hate and violence in this world. We must learn to be more kind, compassionate, empathetic, and sympathetic to humanity.
