These can be summed up under the headings of the French Revolution slogans.

• Liberty. Protect the human rights of victims against gross violations.
• Equality. Treat all states equally, from small to large, from weak to strong, from friends to foes.
• Solidarity. (Less sexist term than fraternity). Loss of life should be considered both for the intervenors and the targets.

These were all violated in the Kosovo case. Victims suffered more after the NATO bombing started. There was no intervention, e.g., in Chechnya. NATO suffered no losses, Serbians and Kosovars many.

It could be argued that “equality” is impossible, because nuclear states like Russia cannot be targetted for fear of triggering nuclear war. Perhaps this problem can be solved in the future.
