Why is humanitarian intervention controversial?

Humanitarian intervention is controversial because it often involves the use of military force in the internal affairs of a sovereign nation, raising questions about state sovereignty and the principle of non-interference. Critics argue that such interventions can lead to unintended consequences, including escalation of conflict and civilian casualties. Additionally, there are concerns about the motivations behind interventions, as they may be influenced by geopolitical interests rather than purely altruistic goals. This complexity makes it difficult to establish a clear moral and legal framework for when and how interventions should occur.
