Although the author concedes that much criticism from the left alleging ulterior imperialist motives of missions for “humanitarian intervention” is valid; nevertheless, the author argues that it would be wrong to rule out the concept of humanitarian intervention, even when conducted by imperialist powers for imperialist motives. The concept of “rescue” remains a valid humanitarian concept, and a logical foundation for solidarity with populations who find themselves under assault and defenseless. The author considers various regulative principles that may guide more careful thinking about humanitarian intervention.
