The Peace Line with Kate Laverty: Just War, Just Peace?

Reclaiming nonviolence in a time of political noise

Recent political commentary in the United States has brought the concept of “just war” back into public debate. Criticism directed at the Pope — alongside interventions from figures like Donald Trump and JD Vance — has framed Christian nonviolence as naïve, even irresponsible, in the face of global threat.

But this framing misunderstands both the history and the depth of the tradition it seeks to invoke.

The idea of “just war” did not emerge as a justification for violence, but as an attempt to restrain it. Rooted in the writings of Augustine of Hippo, it was a moral framework designed to limit when and how force could be used — insisting on necessity, proportionality, and last resort. It was, at its core, an ethic of hesitation.

Over time, however, what was intended as a brake has too often become a permission structure.

The Pope’s recent emphasis on nonviolence is not a rejection of moral responsibility — it is a return to a deeper question: what does it mean to follow a faith rooted in love, dignity, and the refusal to dehumanise?

And Christianity is not alone in grappling with this tension.

In Islam, principles of just conduct in war (jus in bello) emphasise protection of civilians, restraint, and accountability. In Judaism, the concept of milchemet mitzvah (obligatory war) is tightly bound by ethical conditions. In Buddhism, the commitment to non-harm (ahimsa) sits uneasily but persistently alongside historical realities of conflict. Across traditions, there is a shared discomfort — a recognition that violence, even when justified, leaves a moral wound.

So where does that leave us?

The question is not simply whether war can ever be “just,” but whether justice can ever truly be achieved through violence.

Nonviolence does not ignore harm. It confronts it differently. It asks what it would mean to build systems, relationships, and politics that prevent violence long before it becomes thinkable. It shifts the focus from reaction to prevention, from dominance to dignity.

To reconcile just war and nonviolence may not be about choosing one over the other, but about recognising their tension.

Just war says: if force must be used, it must be constrained.

Nonviolence says: we must build a world where it is no longer needed.

In a time when political rhetoric rewards certainty and strength, the harder path is moral complexity — holding the line that human dignity cannot be conditional, even in conflict.
