Just War: theory and application

ABSTRACT How should just war theory be applied to assess a community's claim to defend itself? The IRA's claim to be fighting a just war to end British rule in Northern Ireland is upheld against the objection (e.g. by Simpson in this Journal, 1986) that they have a right only to self-defence against indigenous tyranny. Under just war theory no unclarity concerning the alien status of British rule could render the IRA claim unjustifiable: only the well-grounded denial of its alien status might serve (though this is doubtful). But if that denial is argued for by identifying a separate British community in Ireland then the IRA must be granted a right to repel alien occupation of nationalist areas. However the IRA's rejection of the ‘two communities’ view can be defended; for what constitutes a single community is subject to moral considerations. Accordingly a genuine community's claim to self-defence is against being wronged, rather than harmed. It is concluded that just war theory cannot be applied without antecedent moral judgements identifying the community potentially wronged.
