Diplomatic expulsion of ambassador is a routine foreign policy action with minimal constitutional implications. A-score of 2.65 reflects minor rule_of_law considerations (diplomatic protocol) and separation concerns (executive foreign policy power), but lacks substantial constitutional damage. B-score of 9.38 reflects moderate media interest in diplomatic tensions but insufficient hype for List B threshold. The policy_change mechanism applies but with limited domestic constitutional impact. Narrow population scope (diplomatic corps) and international focus further reduce constitutional relevance. This is standard diplomatic friction, not a constitutional event.
