Complaining of “media bias”, Hamas spokesman Basim Naim denies allegations that its members intentionally murdered civilians and non-combatants in their assault on Israel last week. The operation “targeted only the Israeli military bases and compounds”, he says, and al-Qassam Brigade commanders ordered their troops to “avoid targeting civilians or killing them”.

Given the details, as best we can know them, those claims ring hollow.

So, too, do claims that the Israeli Defence Force — among whose members T-shirts illustrated with a picture of a pregnant Arab woman in rifle crosshairs and the caption “1 Shot 2 Kills” popped up during a previous military confrontation with the Palestinian Arabs — constitutes “the most moral army in the world”.

In declaring a “complete siege” of Gaza — with the intent to cut off food, fuel and electricity to the Arab enclave’s 2.3 million inhabitants while engaging in massive airstrikes on them — Israeli defence minister Yoav Gallant referred to the people he wants murdered as “animals”.

The same is true of the numerous claims by numerous governments and armed forces, in conflicts around the world, that murders of civilians and non-combatants are mere accidents or asides for which they bear no responsibility.

Three moral premises seem fairly basic to me:

• We are individually responsible for what we do

• We are jointly and severely responsible for what we collude with others to do

• We are at least partially responsible for the actions of others when we accept positions of authority from which we may order, allow, forbid, excuse or punish those actions

Phrases such as “collateral damage”, “mistakes were made”, “they did it first” or “I was just following orders” do not magically relieve us of responsibility for our individual, collaborative or organisational actions.

Nor does the claim that one is acting as, or on behalf of, a government. The pernicious doctrine of “qualified immunity” notwithstanding, when a police officer guns down a nonviolent citizen or a drone operator launches a missile into the middle of a wedding party, it’s murder and nothing else.

When you pull a trigger or order that trigger pulled, you are responsible for the consequences. Period. And if your action or order results in injuries or deaths among civilians or non-combatants, there are no acceptable excuses. You should be charged, tried, convicted and punished for your actions.

Unfortunately, that seldom happens. And when it does happen, it is usually just for show, with lower-level killers getting thrown under the bus while generals, presidents and prime ministers skate off to comfortable retirements — the laurels of “statesmen” resting ostentatiously upon their Botox-tightened brows.

Ultimately, the only way to do away with war crimes is to do away with war. And that requires us to first abolish the state.
