Regardless if we started from the old era of empires or when peace was obtained in Westphalia in 1648, International Law has evolved since into these set of principles and customs that over time, were accepted not only by a single civilization, but that of the community of nations – later on becoming the collective description of the Law of Nations. As of this writing, International Law provided, and still provides, the enduring set of legal principles and norms for the maintenance of the justice and balance of relationships between and among States. While there are opportunities to change particular established principles and norms over time, most of the issues, conflicts and disputes among States are resolved with the traditions and formalities that also endured over time. Similarly, the traditions of these principles and norms within State policies and practices, such as sovereign immunities and privileges among States and pacta sunt servanda, still remain as a time-tested and enduring practice among States.
