“A government of laws, and not of men.”
John Adams (1774)
Incoming US president Donald J. Trump’s obeisance to Russia’s Vladimir Putin is well-documented. Such behavior is sometimes much more serious than a matter of personal dereliction. In consideration of Putin’s ongoing crimes against Ukraine, [1] it represents a time-urgent matter of law and justice. Though unknown to most Americans, including practicing lawyers and members of Congress, violations of international law (aka “the law of nations”) are generally violations of United States law.
On multiple occasions, Donald Trump and his key advisors have referenced the United States as “a nation of laws.” In vacuo, this uplifting phrase offers a reassuring mantra, but it is not one that is self-authenticating. Even before the start of his second administration, Mr. Trump is urging a “deal” between Russia and Ukraine in which (1) the victim of aggression must negotiate “peace” with the criminal perpetrator; and (2) the United States is openly on the side of the aggressor.
Credo quia absurdum, said the ancient Roman jurist Tertullian: “I believe because it is absurd.” Historically and jurisprudentially, it’s as if the 1938 Munich surrender of Czechoslovakia to Adolf Hitler never happened or that the United States was somehow not the lead prosecuting state at Nuremberg in 1945-46. [2] Because international law is part of the law of the United States, [3] negotiating over Putin’s aggression would simultaneously undermine US law. Among other things, such indifference would make the United States complicit in crimes against peace (aggression), [4] crimes of war (humanitarian international law [5]) and crimes against humanity [6] (genocide). [7]
Under international law, ipso facto, Russian crimes against Ukraine must be punished and reversed, never appeased. In words reaffirmed at Nuremberg, a core principle of justice is always Nullum crimen sine poena, “No crime without a punishment.” Jurisprudentially, President-elect Donald Trump’s demand that the victim state “make a deal” with the aggressor for return of its own stolen territory lies far beyond any authoritative limits.
Even in our state-based system of international law – the sovereignty-centered system brought into being at the Peace of Westphalia in 1648 [8] – a presumption of global community and solidarity ultimately overrides the prerogatives of sovereignty. Following unambiguous legal expectations amplified by the post-World War II Nuremberg Judgment and Principles, states have not only the right but the obligation to intervene on behalf of basic human rights. Because such obligation is jus cogens or “peremptory,” and may stem from a “higher law,” it is binding and overriding. [9]
There is more. In formal legal terms, the harms that Russia is continuously inflicting on Ukraine represent criminal behavior of “international concern.” Accordingly, every state member of the community of nations has the right and the obligation to stand against the Russian aggressor and with the Ukrainian victim. Scholars and policy-makers can find conspicuous support for this core imperative in classical legal writings of Cicero, Hugo Grotius, Samuel Pufendorf and Emmerich de Vattel. Though such names will be unrecognizable to President-elect Donald J. Trump, his official appointments and to most Members of Congress, they were well known to Founding Fathers of the United States. Now, it is high time that such people who ritually proclaim this government as one “of laws, not of men” be reminded: Both international law and US law are drawn from a timeless and universal “law of nature” (aka “natural law” or “higher law”). [10]
By definition, the natural law origins of the United States can never be reasonably challenged or permissibly abrogated. Vladimir Putin’s Nuremberg-category crimes not “only” undermine international law’s binding human rights regime, they also enlarge risks of a nuclear war. [11] On its face, should such a war ever result from an American government’s urging Ukraine to negotiate over Putin’s crimes of war, crimes against peace and crimes against humanity, that unprecedented outcome would represent the ultimate violation of civilized international relations.
There is still more pertinent legal background. An aspiring US president could consult Book 2 of Emmerich de Vattel’s encyclopedic “The Law of Nations” (1758): Says Vattel: “If there should ever be found a restless and unprincipled nation, every ready to do harm to others, to thwart their purposes and to stir up civil strife among their citizens, there is no doubt that all other states would have the right to unite together to subdue such a nation, to discipline it, and even to disable it from doing further harm.”
Donald J. Trump’s unhidden indifference to Russian crimes against Ukraine falls unequivocally short of his upcoming obligations under both international and US law. If there should still remain any law-respecting doubters of this shortfall, they need only recall the explicit language of the UN’s Statute of the International Court of Justice (1945). Article 38 describes “the general principles of law recognized by civilized nations” as a fully primary source of international law. [12]
Gabriela Mistral, the Chilean poet who won the Nobel Prize for literature in 1945, affirmed that crimes of war, crimes against peace and against humanity carry within themselves “a moral judgment over an evil in which every feeling man and woman concurs.” In his casual defiance of this “moral judgment,” Donald Trump seems wittingly inclined to ignore correlative obligations under US and international law. [13] If there should remain any political figures or scholars who don’t acknowledge a need to condemn such baseless indifference, they ought to look back over the doctrinal foundations of relevant jurisprudence, including the specific American legal claim to “a government of laws, not of men.”
There are further details. International law includes norms of customary as well as codified nature. Article 38(1)(b) of the Statute of the International Court of Justice describes international custom as “evidence of a general practice accepted as law.” Moreover, the norms of customary international law bind all states irrespective of whether a particular state has ratified the codifying instrument or convention.
International law compartmentalizes the apparently identical rights and obligations that arise from customary law and treaty law: “Even if two norms belonging to two sources of international law appear identical in content, and even if the states in question are bound by these rules both on the level of treaty-law and on that of customary international law, these norms retain a separate existence.” [14]
When Donald J. Trump re-enters the White House in January 2025, a first order of business should be formal reaffirmation of the territorial sovereignty and independence of Ukraine. To act otherwise, to support the inherently unjust claims of the world’s most conspicuous “common enemy of humankind” (in law, a “hostes humani generis”) would defile America’s founding principles of justice. [15] In the final analysis, whether the United States is genuinely “a government of laws, and not of men” will depend on the wisdom and integrity of its citizens. [16]

[3] In the words of Mr. Justice Gray, delivering the judgment of the US Supreme Court in Paquete Habana (1900): “International law is part of our law, and must be ascertained and administered by the courts of justice of appropriate jurisdiction….” (175 US 677(1900)) See also: Opinion in Tel-Oren vs. Libyan Arab Republic (726 F. 2d 774 (1984)). The specific incorporation of treaty law into US municipal law is expressly codified at Art. 6 of the US Constitution, the so-called “Supremacy Clause.”
[4] Following the Kellogg-Briand Pact of 1928 and the United Nations Charter (1945), there remains no defensible legal right to waging an aggressive war. However, the long-standing customary right of post-attack self-defense does remain codified at Article 51 of the UN Charter. Similarly, subject to conformance, inter alia, with jus in bello criteria, certain instances of humanitarian intervention and collective security operations may also be consistent with jus ad bellum standards. The law of war, the rules of jus in bello, comprise: (1) laws on weapons; (2) laws on warfare; and (3) humanitarian rules. Codified primarily at The Hague and Geneva Conventions, these rules attempt to bring discrimination, proportionality and military necessity into all belligerent calculations.
[5] Humanitarian international law, or the laws of war, comprise: (1) laws on weapons; (2) laws on warfare; and (3) humanitarian rules. Codified primarily at The Hague and Geneva Conventions, and known thereby as the law of The Hague and the law of Geneva, these rules seek to bring discrimination, proportionality and military necessity into belligerent calculations. On the main corpus of jus in bello, see: Convention No. IV, Respecting the Laws and Customs of War on Land, With Annex of Regulations, Oct. 18, 1907, 36 Stat. 2277, T.S. No. 539, 1 Bevans 631 (known commonly as the “Hague Regulations”); Convention for the Amelioration of the Condition of the Wounded and Sick in Armed Forces in the Field, Aug. 12, 1949, 6 U.S.T. 3114, T.I.A.S. No. 3362, 75 U.N.T.S. 85; Convention Relative to the Treatment of Prisoners of War, Aug. 12, 1949, 6 U.S.T. 3316, T.I.A.S.

[6] Crimes against humanity are defined as “murder, extermination, enslavement, deportation, and other inhumane acts committed against any civilian population before or during a war; or persecutions on political, racial or religious grounds in execution of or in connection with any crime within the jurisdiction of the Tribunal, whether or not in violation of the domestic law of the country where perpetrated….” Charter of the International Military Tribunal, Aug. 8, 1945, Art. 6(c), 59 Stat. 1544, 1547, 82 U.N.T.S. 279, 288.
[7] Neither international law nor US law specifically advises any particular penalties or sanctions for states that choose not to prevent or punish genocide committed by others. Nonetheless, all states, most notably the “major powers” belonging to the UN Security Council, are bound, among other things, by the peremptory obligation (defined at Article 26 of the Vienna Convention on the Law of Treaties) known as pacta sunt servanda, to act in continuous “good faith.” In turn, this pacta sunt servanda obligation is itself derived from an even more basic norm of world law. Commonly known as “mutual assistance,” this civilizing norm was most famously identified within the classical interstices of international jurisprudence, most notably by the eighteenth-century legal scholar, Emmerich de Vattel in The Law of Nations (1758).
[8] International law remains a “Westphalian” system. See: Treaty of Peace of Munster, Oct. 1648, 1 Consol. T.S. 271; and Treaty of Peace of Osnabruck, Oct. 1648, 1., Consol. T.S. 119, Together, these two treaties comprise the Peace of Westphalia.
[9] The United States Constitution is based on the idea of a “higher law.” See: Edward S. Corwin, “The `Higher Law’ Background of American Constitutional Law” (Cornell, 1928). Says Corwin, America’s constitutional democracy is “a system of government in which “the wielders of power are held in check by the rule of law.” (Preface). Such a system, prima facie, is always “a government of laws, and not of men.” This idea of a “higher law,” the American Founders already knew from Blackstone (Commentaries) is “eternal and immutable,” a system “to which the creator himself must conform.”
[10] Under international law, the idea of “natural law” or “higher law” was drawn originally from the philosophic writings of ancient Greeks and Hebrews (Torah Law), and is contained, inter alia, within the principle of jus cogens or “peremptory” norms. According to Article 53 of the Vienna Convention on the Law of Treaties: “…a peremptory norm of general international law is a norm accepted and recognized by the international community of states as a whole as a norm from which no derogation is permitted and which can be modified only by a subsequent norm of general international law having the same character.” See: Vienna Convention on the Law of Treaties, Done at Vienna, May 23, 1969. Entered into force, Jan. 27, 1980. U.N. Doc. A/CONF. 39/27 at 289 (1969), 1155 U.N.T.S. 331, reprinted in 8 I.L.M. 679 (1969).

[13] Inter alia, United States law is deducible from natural law. According to Blackstone, each state and nation is always expected “to aid and enforce the law of nations, as part of the common law, by inflicting an adequate punishment upon offenses against that universal law….” See: 2 William Blackstone, Commentaries on the Laws of England, Book 4, “Of Public Wrongs.” Lest anyone ask about the significance of Blackstone, one need only point out that his Commentaries represent the original and core foundation of United States law.

[15] “Justice,” America’s founders learned originally from Plato’s Republic, “is a contract neither to do nor to suffer wrong.”
[16] For original of this phrase, see John Adams, Novanglus Papers, No. 7 (1774). Adams likely drew this phrase from 17th century English political philosopher James Harrington. He later used it in the Declaration of Rights drafted specifically for the Massachusetts Constitution (1780).
