The research discusses the impact of humanitarian intervention by resolution of the UN Security Council or General Assembly. Humanitarian intervention is considered an exception, as the principle of public international law is non-interference and the preservation of state sovereignty. This is because sovereignty is the most important principle and foundation upon which public international law is based. Therefore, this intervention has a significant impact on the sovereignty of states and their relations with other states. The importance of this research stems from its understanding of the principle of humanitarian intervention from its various legal aspects, its impact on state sovereignty, and its attempt to clarify the principle of intervention and remove the ambiguity surrounding the relationship between humanitarian intervention and the principle of sovereignty. The main problem of this research revolves around the conflicting idea of international humanitarian intervention and its impact on state sovereignty, and the impact of the principle of humanitarian intervention on the future of the state in whose affairs the intervention is taking place, whether at the domestic or international levels. This problem raises research questions, the most important of which are: What is the impact of international humanitarian intervention and its impact on international sovereignty? This research aims to analyze the legal and ethical basis for intervention, including the United Nations Charter, the impact of humanitarian intervention on national sovereignty, and the cases in which humanitarian intervention is exploited to attack independent states, interfere in their internal affairs, and pressure them to implement their wishes. This research will follow a descriptive-analytical approach, which involves examining the topics through analyzing, describing, and clarifying jurisprudential opinions and legal texts contained in the United Nations Charter and other international norms. The research reaches several conclusions, the most important of which are: The principle of humanitarian intervention is a modern-day weapon against dictatorial regimes that violate human rights, requiring them to reconsider their democratic system in line with the contemporary international order. International humanitarian intervention may negatively impact the state in whose affairs the intervention is taking place, transforming it from a fully sovereign state with its authority and influence on the international scene into a state with incomplete sovereignty that acts under the orders of another state, not only internationally but also domestically. The double standards of international humanitarian intervention are clear. The international community has intervened in places where it should not have done so, such as Iraq, while standing silently by and watching real and actual human rights violations, such as in Gaza.
