“We do not negotiate with terrorists” is an attractive political slogan. It promises resolve, denies legitimacy to those who attack civilians and reassures the public that violence will not be rewarded. Yet it avoids the harder moral question. If talking to a terrorist organisation could prevent further deaths, is refusing to do so really principled? Conversely, if negotiation strengthens that organisation or provokes more violence, can talks still be defended as the humane choice? The moral problem is not simply whether terrorists deserve a place at the table. It is whether governments should risk legitimising violence in order to end it. Every available course therefore risks either compromising a principle or allowing foreseeable harm to continue without challenge.
To answer this, we must distinguish talking from negotiating. A government can communicate secretly through a back channel without recognising a terrorist organisation as a legitimate political representative. Such contact might be used to exchange information, communicate limits, arrange a temporary ceasefire or discover whether compromise is possible. Formal negotiations are different. They are public, confer status on participants and normally involve some willingness to make concessions. It is therefore possible to believe that governments should always remain capable of talking while accepting that formal negotiations are not always morally justified.
The strongest argument for maintaining contact is the duty to protect life. After the attacks of 11 September 2001, President George W. Bush insisted that the United States could not negotiate with terrorists. The alternative was a military campaign intended to defeat them. Yet the post-9/11 wars killed hundreds of thousands of civilians and displaced millions more. Force may sometimes be necessary, but it rarely harms only its intended targets. A policy that refuses dialogue in order to demonstrate moral strength can therefore impose its greatest cost on people who had no responsibility for terrorism.
Nor does talking necessarily reward violence. British governments maintained secret contacts with the Irish Republican Army before the peace process that produced the Good Friday Agreement. Spanish governments also communicated with the Basque separatist organisation ETA. In both cases, contact did not mean approving bombings or accepting every political demand. It allowed governments to determine whether armed groups could make credible commitments and whether violence might be brought into a political process. An absolute refusal to talk would have removed an avenue through which these conflicts could eventually be reduced.
However, moving from contact to formal negotiation creates a different moral danger. Granting an armed organisation political access may appear to teach that violence succeeds where peaceful campaigning fails. Negotiations can also give militants time to recruit, reorganise and rearm. Most seriously, a peace process can provoke actors who believe that compromise betrays their cause. These “spoilers” may deliberately escalate violence to destroy trust between the negotiating parties.
The Israeli-Palestinian peace process illustrates this danger. In 1994, during negotiations between Israel and the Palestine Liberation Organisation, the extremist Baruch Goldstein murdered 29 Muslim worshippers at the Ibrahimi Mosque in Hebron. Similarly, Hamas engaged in large-scale spoiler violence in 1995 with the express aim of undermining the negotiations, including 3 incidents of public bus bombings. The massacres contributed to retaliatory violence and deepened hostility around the peace process. In Northern Ireland, the ‘Real IRA’ formed as a spoiler group to reject the Good Friday Agreement and continued bombing civilians. In each case, attempts to create peace were met by groups seeking to make peace impossible. Negotiation was not necessarily the cause of their violence, but governments have a moral responsibility to anticipate the risk.
The aims and organisation of the terrorist group also matter. A meaningful settlement requires participants who can identify achievable demands, control at least a substantial part of their movement and accept something short of total victory. A government cannot reasonably negotiate over its own destruction, nor can an organisation deliver peace if its negotiators have no authority over those committing violence. Even where a settlement is possible in principle, the timing may be wrong. Public talks launched without sufficient preparation can expose civilians to backlash while offering little prospect of an agreement.
This is why moral and practical considerations cannot be cleanly separated. If the moral purpose of engagement is to minimise bloodshed, governments must consider the likely consequences of different forms of contact. Talking might save lives, but public negotiation might place them at greater risk. Equally, the possibility of failure cannot excuse permanent silence, because silence leaves force as the principal means of responding.
Governments should therefore always preserve channels of communication with terrorist organisations, but enter formal negotiations only under defensible conditions. They should ask whether the group can compromise, whether its representatives can enforce an agreement, whether civilians can be protected from spoilers and whether talks have a credible prospect of reducing violence. The morally serious position is neither automatic negotiation nor absolute refusal. It is a willingness to talk without illusion, combined with a duty to judge when negotiation is more likely to end bloodshed than extend it.
