An international norm is being breached one way or the other the only question is which one is to be breached. Those in favour of intervention consider that lives saved is worthwhile compared to the problems the breach of a norm against humanitarian intervention might create. All of these norms are there with the intention of saving lives; that is what a norm of preventing any infringement of sovereignty without UN approval is supposed to prevent – conflict and the lives lost this causes. But Internal conflict and genocide has since become much more the problem than aggression between states requiring a rebalancing of which norms are kept.
