The alternative to universalism is not an extreme individualism. Any possible, and certainly any desirable, life is social. We can see each individua… - J. L. Mackie

Mankind is not an agent; it has no unity of decision; it is therefore not confronted with any choices.

Life is, fortunately, not a continuous application of game theory.

Notoriously, there are disputed territories — for example, border areas and regions occupied by groups which are not independent nations, but many of whose members wish that they were. Again, there are territories like that which used to be called Palestine; here the principles which in the case of Norway point univocally to one national group as that to which the area belongs diverge, some supporting the claims of the Israelis and others the claims of the Palestinian Arabs. Cyprus and Northern Ireland are two other obvious examples of conflicting prima facie rights of distinguishable national groups. In such cases the appeal, by both parties to a dispute, to supposedly absolute rights is disastrous. It reduces the readiness to negotiate and compromise, and it seems to justify any atrocities against the enemy, and any resulting losses and suffering for one's own side, that are needed to vindicate those rights.
