Alliance, in international relations, a formal agreement between two or more States on mutual assistance in the event of war. Contemporary alliances provide for joint action by two or more independent states and are generally defensive and force allies to regroup when one or more of them are attacked by another state or coalition. Although alliances can be informal, they are usually formalized by a treaty of alliance whose most critical clauses are those that define casus foederis or the circumstances in which the treaty commits one ally to help another. A treaty is negotiated by a group of countries, either by an organization created for that purpose or by an existing body such as the United Nations Disarmament Council (UN). The negotiation process can take several years depending on the subject of the contract and the number of participating countries. At the end of the negotiations, the treaty will be signed by representatives of the governments concerned. The conditions may be that the treaty be ratified and signed before it becomes legally binding. A Government ratifies a treaty by presenting an instrument of ratification at a place determined by the treaty; The instrument of ratification is a document containing the formal confirmation of the adoption by the Government of the provisions of the Treaty. The ratification process varies according to national law and constitution. In the United States, the president can only ratify a treaty after obtaining the «consultation and approval» of two-thirds of the Senate. an agreement between two or more persons, groups or countries by which they undertake to cooperate with a view to achieving results unless a treaty controls other agreements or measures, only the text of the treaty is legally binding. Generally speaking, a treaty amendment is binding only on States that have ratified the amendment and agreements reached at review conferences, summits or meetings of States parties are political, but not legally binding.
The Charter of the United Nations is an example of a treaty that contains provisions relating to other binding agreements. By signing and ratifying the Charter, countries have agreed to be legally bound by resolutions adopted by UN bodies such as the General Assembly and the Security Council. Therefore, UN resolutions are legally binding on UN Member States and no signature or ratification is required. a formal written agreement between two or more countries. When national leaders negotiate a treaty, they discuss it before reaching an agreement; and, when they ratify a treaty, they give its formal consent, usually by signature or vote. Approval is still valid if it is given by a representative who has ignored the restrictions to which he is subject by his sovereign during the negotiations, if the other parties have been informed of these restrictions before signing.
