The institution designed to prevent this was the Senate’s advice-and-consent power over treaties and military commitments - specifically, the principle that the United States cannot unilaterally abrogate or renegotiate alliance obligations without legislative participation. It failed because executive pronouncements, however authoritative, have been treated as sufficient substitutes for formal consultation, and because the legislative branch has ceded its oversight function not through obstruction but through silence, mistaking absence of resistance for consent.

Here is what strikes the observer first: a single voice declaring the end of a war in timeframes shorter than a planting season, while others in the same administration suggest the United States might reconsider its most enduring security compact. The dissonance is not merely rhetorical - it reveals a structural gap. In the American system, the power to declare war resides with Congress, but so too does the power to ratify treaties and approve alliances. The executive may direct troops, but it cannot unilaterally redefine the conditions of its own security architecture. Yet in this moment, the executive speaks as though it alone determines when a war ends and whether an alliance serves its interests - as though NATO were not a treaty binding the United States to the defense of its members, but a contractual arrangement subject to renegotiation at the pleasure of the Secretary of State or the President.

Compare this with the British experience after 1689. The Bill of Rights explicitly reserved the power to raise armies and conclude treaties to Parliament. When Charles II attempted to negotiate secret treaties with France, Parliament did not merely protest - it embedded oversight into the fabric of government. The Triennial Act ensured regular meetings; the Mutiny Act made annual parliamentary approval a condition of military funding. The result was not perfect peace, but a system where no single minister could commit the realm to war or peace without a counterweight. The American founders, reading this history closely, designed their constitution to avoid the very trap they saw in France, where the king concluded treaties without the Estates-General and thus committed the nation to wars it could not afford or justify.

In the present case, the Strait of Hormuz - a narrow passage through which a significant portion of the world’s oil passes - has become a bargaining chip not in diplomacy, but in domestic political theater. The suggestion that nations relying on the Strait must “reopen” it themselves, as though they were tenants responsible for fixing the landlord’s gate, reveals a fundamental misunderstanding of maritime law and collective security. The freedom of navigation in international waters is not a favor granted by a single nation, however powerful; it is a custom refined over centuries, codified in part by the United Nations Convention on the Law of the Sea. To treat it as a matter of bilateral negotiation - or worse, as a lever to be wielded against allies - is to risk the erosion of the very principle that has kept global trade flowing since the Dutch Republic first challenged Portuguese and Spanish monopolies.

What check remains? The Senate’s ratification power exists on paper, but it has not been exercised - not because it is impossible, but because no one has invoked it. The check is dormant, not defeated. And that is the greater danger: a check that is never tested may not stand when it is needed. The British learned this in the 1760s, when Parliament assumed the right to tax the colonies without their consent, believing its supremacy unassailable - until the colonies, having no voice in the legislature that governed them, decided to govern themselves.

The principle at stake is not loyalty to a treaty or loyalty to an ally, but the principle that no single person - however persuasive, however popular - may redefine the conditions of national security without the consent of those who share the burden of that security. The executive may speak, but it is Congress that must speak back - not to obstruct, but to deliberate. To allow the president to set the timeline for war’s end while the Senate debates alliance terms in the abstract is to invite confusion, not clarity; to invite skepticism, not credibility.

The question is not whether the United States should remain in NATO - though that is a question worth asking - but whether the decision, if made, will be made through the institution designed to make such decisions: a deliberative body representing the people, not a single voice speaking for the nation. The structure is sound. It is the citizens - and their representatives - who have forgotten how to use it.
