International crises can significantly affect domestic political stability by creating fear, uncertainty, and often leading to a rally-around-the-flag effect. National emergencies may prompt swift governmental actions, weakening institutional checks and balances. However, prolonged crises can also lead to public dissatisfaction with incumbents, resulting in political upheaval or shifts in power dynamics, as citizens demand accountability or reforms. Overall, while crises can temporarily unify a nation, they often expose underlying tensions and vulnerabilities within the political system.
