Common arguments for partitions include:
- historicist – that partition is inevitable, or already in progress
- last resort – that partition should be pursued to avoid the worst outcomes (genocide or large-scale ethnic expulsion), if all other means fail
- cost–benefit – that partition offers a better prospect of conflict reduction than the if existing borders are not changed
- better tomorrow – that partition will reduce current violence and conflict, and that the new more homogenized states will be more stable
- rigorous end – heterogeneity leads to problems, hence homogeneous states should be the goal of any policy
