If nations have legitimacy then they can enter into supra-/international bodies and agreements with legitimacy much like two persons can agree on an arbiter to resolve differences in their mutual contracts. This is nothing new and we've been doing it for a long time—the Egyptian 18th dynasty entered into the first known peace treaty with a foreign nation 1500 years BCE; NATO and the United Nations are modern examples. The US, of course, is a country that has been notoriously difficult to get into international agreements (Paris/Kyoto, WHO, ICC).
