Upon independence from Great Britain, the United States "were bound to receive the law of nations, in its modern state of purity and refinement. Ware v. Hylton, 3 Dall. 199. 199, 281 (1796). In The Nereide, Justice Marshall stated that the “Court is bound by the law of nations, which is part of the law of the land.” 13 U.S. 388, 423 (1815). “The courts have always considered the law of nations to be part of the law of the United States.” M. J. Glennon, Constitutional Diplomacy (Princeton, NJ: Princeton University Press 1990), at 245. There are numerous other authorities that state that the law of nations became the national law of the United States. Even William Blackstone recognized the importance of the law of nations which he considered "universal law" and the life blood of a nation wanting to be part of the "civilized world." 4 W. Blackstone, Commentaries on the Laws of England 67 (1769). Hence, the law of nations, when not codified into any Act of Congress, became the common law of the United States
