The term "police action" has been used by various countries to describe their military interventions in other countries. However, due to the negative connotations associated with the phrase, different synonyms have been developed over time. These include "peacekeeping operation," "humanitarian intervention," "enforcement action," "security intervention," and "military operation." These alternative phrases aim to convey less aggression and more of a sense of humanitarian or peacekeeping efforts. The use of these synonyms often reflects the political motives behind the operation as well as the desire to legitimize military actions to the public.
