How does the UN Charter protect countries from being forced into wars by allies?

The UN Charter, particularly Article 2(4), prohibits the threat or use of force against the territorial integrity or political independence of any state, serving as a cornerstone of international law that prevents countries like Britain from being coerced into wars by allies such as the US. This principle ensures that military action is only permissible in self-defense (under Article 51) or with explicit authorization from the UN Security Council. In the context of US-Iran tensions, if the US were to initiate a conflict without such justification, Britain would not be legally obligated to participate. The Charter reinforces state sovereignty, meaning each nation must independently assess the legality and necessity of joining a war. This legal barrier is bolstered by domestic laws in many countries, including the UK's constitutional requirements for parliamentary approval in non-emergency military actions. As a result, the UN Charter acts as a critical safeguard, allowing Britain to resist political pressure and avoid unlawful entanglement in conflicts, thereby maintaining international peace and security.
