We are quick—too quick—to say that Congress abandoned its role in foreign policy years ago, and that there is therefore nothing new in a president acting alone.
It is a convenient argument. It is also an incomplete one.
Presidents have, in fact, gone to Congress for authorization in the major conflicts of the modern era. Vietnam proceeded under the Gulf of Tonkin Resolution. Iraq was authorized twice, in 1991 and again in 2002. Afghanistan followed the 2001 Authorization for Use of Military Force. Even in Syria, when Barack Obama sought broader action, he went to Congress—and when Congress declined, he adjusted accordingly.
The record is not one of perfect constitutional discipline. But neither is it one of abandonment.
Korea stands as the principal exception—a war conducted under the auspices of the United Nations without formal congressional authorization. Even there, Congress did not so much resist as acquiesce, having already accepted the obligations of the UN framework.
This history matters, because it reveals something often overlooked:
Process has been strained, but until recently, not bypassed.
What is different now is not merely the use of force, but the absence of even the attempt to legitimize it through Congress.
Recent actions—in Venezuela, in Iran, and in a series of smaller conflicts—have proceeded without prior authorization, and often without meaningful public deliberation. Congress is informed, sometimes after the fact. Debate follows, if at all. But the decision itself has already been made.
We tell ourselves this is nothing new. That presidents have always stretched their authority. That Congress prefers to avoid difficult votes.
There is truth in all of that.
But there is a difference—no small one—between a system under strain and a system set aside.
The constitutional design was not accidental. The framers understood that the decision to go to war is the most consequential a republic can make. They placed it not in the hands of one person, but within a process—deliberative, imperfect, and shared.
Not because Congress is wiser.
But because the act of deliberation disciplines power.
To be sure, there are moments when urgency compresses time, when threats do not wait upon procedure, and when a president must act before consensus can be assembled. No serious observer denies this.
But necessity was never meant to become habit.
When process is routinely bypassed, something more than procedure is lost. The country is denied a moment of collective judgment. The world is denied clarity about American purpose. And the military is sent into action without the full weight of national consensus behind it.
In recent years, too much has been left to instinct—sometimes defended on the grounds that voters chose it.
Perhaps they did.
But a republic is not sustained by instinct alone. It is sustained by habits, by institutions, and by a willingness to submit even urgent decisions to a broader test.
We should be asking, again and seriously:
What does the Constitution require?
What does prudence advise?
What serves not merely immediate advantage, but long-term stability—for the United States and for the world it helps shape?
These are not antiquarian questions. They are the operating principles of self-government.
Because the manner in which a great power goes to war is not a procedural detail.
It is a signal—to its citizens, to its soldiers, and to the world—of what kind of country it intends to be.
And when a nation ceases to deliberate before it fights, it begins, however subtly, to change what it is.
