Earlier quoted context omitted.
American states are sovereign entities. This is very well understood in Constitutional law, albeit a little confusing for the laymen as the common understanding of sovereignty would be something like, well France is sovereign because it has an army and it conducts trade and all of those sorts of sovereign things. But US states are sovereign entities who have, effectively, joined together to delegate some of their sov…
No, US States are not sovereign entities. They have no ability to conduct independent international diplomacy. They do not have independent militaries, and they have no right to secede. The supremacy clause (article 7) makes it clear that states cannot override federal law. With the way you’re characterizing the idea of sovereignty, every entity in the world is semi-sovereign. But sovereignty isn’t a spectrum. An ent…

"Although the Constitution establishes a National Government with broad, often plenary authority over matters within its recognized competence, the founding document "specifically recognizes the States as sovereign entities." Seminole Tribe of Fla. v. Florida, supra, at 71, n. 15; accord, Blatchford v. Native Village of Noatak, 501 U. S. 775, 779 (1991) ("[T]he States entered the federal system with their sovereignty intact"). Various textual provisions of the Constitution assume the States' continued existence and active participation in the fundamental processes of governance. See Printz v. United States, 521 U. S. 898, 919 (1997) (citing Art. III, § 2; Art. IV, §§ 2-4; Art. V). The limited and enumerated powers granted to the Legislative, Executive, and Judicial Branches of the National Government, moreover, underscore the vital role reserved to the States by the constitutional design, see, e. g., Art. I, § 8; Art. II, §§ 2-3; Art. III, § 2. Any doubt regarding the constitutional role of the States as sovereign entities is removed by the Tenth Amendment, which, like the other provisions of the Bill of Rights, was enacted to allay lingering concerns about the extent of the national power. The Amendment confirms the promise implicit in the original document: "The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people." U. S. Const., Amdt. 10; see also Printz, supra, at 919; New York v. United States, 505 U. S. 144, 156159, 177 (1992). The federal system established by our Constitution preserves the sovereign status of the States in two ways. First, it reserves to them a substantial portion of the N ation's primary sovereignty, together with the dignity and essential attributes inhering in that status. The States "form distinct and independent portions of the supremacy, no more subject, within their respective spheres, to the general authority than the general authority is subject to them, within its own sphere." The Federalist No. 39, p. 245 (C. Rossiter ed. 1961) (J. Madison).
"Second, even as to matters within the competence of the National Government, the constitutional design secures the founding generation's rejection of "the concept of a central government that would act upon and through the States" in favor of "a system in which the State and Federal Governments would exercise concurrent authority over the people who were, in Hamilton's words, 'the only proper objects of government.'" Printz, supra, at 919-920 (quoting The Federalist No. 15, at 109); accord, New York, supra, at 166 ("The Framers explicitly chose a Constitution that confers upon Congress the power to regulate individuals, not States"). In this the Founders achieved a deliberate departure from the Articles of Confederation: Experience under the Articles had "exploded on all hands" the "practicality of making laws, with coercive sanctions, for the States as political bodies." 2 Records of the Federal Convention of 1787, p. 9 (M. Farrand ed. 1911) (J. Madison); accord, The Federalist No. 20, at 138 (J. Madison and A. Hamilton); James Iredell: Some Objections to the Constitution Answered, reprinted in 3 Annals of America 249 (1976).
"The States thus retain "a residuary and inviolable sovereignty." The Federalist No. 39, at 245. They are not relegated to the role of mere provinces or political corporations, but retain the dignity, though not the full authority, of sovereignty."
