It has always been the moral case that when a civilized country determines that for the sake of self-protection and survival it must retaliate against aggression or embark on war, the primary goal of its military should be the destruction of that which targets and threatens the country, be it weapons or commandos. The foremost duty of that nation’s leader is to prioritize the lives and safety of those he has sent into combat.
This often forces an uncomfortable but necessary choice: minimizing the risk to one’s troops at the expense of the fighters and population of the enemy. This is not only a civic and military responsibility, but the moral one as well, for the first principle of morality is fulfilling a commitment to those for whom one has freely chosen to be responsible. A leader has a special obligation to the people who chose and trusted him, an obligation that must surpass his feelings for general mankind.
The same still holds true in today’s self-defense against Islamic terrorism, where terrorists purposely fight not in remote battlefields, but specifically in cities among civilian populations diabolically used as shields. In all circumstances, the war of self-defense and survival is a Just war.
The maxim of self-defense is not an abstract platitude, but a raw, real-life imperative. Self-defense means the right to kill a soldier or civilian coming at you before they kill you.
A self-defense that is conditioned on excessive caution not to harm those pursuing you is a rejection of the whole notion of self-defense. Is it possible that the rules of engagement for Americans in Iraq and Afghanistan and for Israelis in Jenin and now Gaza – designed to spare harm to civilians – have led to greater death and injury among their warriors, resulting in a lapse in our obligation to those troops?
Once engaged in a just war, combat should fall within the parameters of moral combat. The primary moral combat standard is to not specifically target truly innocent civilians, to refrain from using civilians as shields, and to forswear torturing the enemy for the sake of cruel pleasure or revenge.
Guaranteeing that civilians not be killed in collateral damage has never been a requisite for moral combat. If such was the case regarding conventional warfare, then it is certainly so when confronted by Islamic terrorism that uses civilian human shields as a strategy to freeze its Western opponents. All agree that rape, looting and blood lust are anathema to moral standards, activities too often relished by jihadists. Proportionality in war is thoroughly doing that which needs to be done to permanently remove the source and scourge of aggression.
