Today a senator who should know better declared on a Sunday news show that “Cuba is next.” A few days earlier, the usually careful David Brooks remarked that we will now have to see whether the strategy toward Iran “works.”
When rhetoric reaches this point, something important has already slipped away: the careful language that once distinguished diplomacy from the anticipation of the next war. The language of statecraft begins to sound less like persuasion and more like prediction. And it becomes difficult to imagine how the rest of the world hears us.
From outside our borders, the central question must be simple: how do we decide who the “bad actors” are?
Iran has long been treated as one. The hostility between the United States and Iran has lasted for decades, and Tehran has often done little to improve its reputation. But the principle now being asserted appears broader than any single country.
Take Cuba. It is hardly known as an exporter of terrorism; its most visible exports are doctors and baseball players. Cuban troops last fought abroad decades ago during the Cold War. Yet now the country is casually mentioned as a potential next target.
If the issue is repression at home, observers abroad may also notice that democracies themselves show signs of strain. When leaders speak of limiting the press, questioning elections, or sending masked agents into cities to demand identification, the distinction between democratic confidence and democratic anxiety can begin to blur.
Other nations inevitably compare this rhetoric with our relationships elsewhere. Russia invaded Ukraine. Saudi Arabia’s leadership oversaw the brutal killing of a journalist. Turkey suppressed a domestic rebellion with considerable force. Each action drew criticism, but none produced serious calls for military confrontation.
There are certainly bad actors in the world. But the question other countries ask is simple: what distinguishes those who face force from those who do not?
From another perspective, some nations might view unilateral—or even bilateral—military action against Iran without broad international consultation, without a case presented to the United Nations, and without sustained domestic debate as its own form of questionable conduct.
Perhaps the moment for restraint has already passed. Wars often acquire their own momentum once begun. It becomes harder to return to the slower system of diplomacy—of coalition building, United Nations deliberation, and the frustrating patience required to maintain international order.
Yet that system existed for a reason.
It reflected the understanding that a world governed purely by power invites every nation to test its strength. Weapons themselves are not illegal in international life; North Korea possesses them, and Russia possesses them. The international system survives not by eliminating power, but by regulating how it is used.
For that reason, democracies have always been expected to speak differently about war—not more softly, but more deliberately.
The United States remains the most powerful nation in the world. But power alone has never been the foundation of its influence. Legitimacy, alliances, and persuasion have always mattered just as much.
We too live with vulnerabilities: an open society, a fragile electrical grid, and an economy tied closely to global cooperation. The precedent we establish today is one that others may invoke tomorrow.
Strength is necessary in international affairs. But even the strongest country benefits from speaking—and acting—as though it still belongs to a community of nations.
And that, in the end, is what the rest of the world is watching: not simply what the United States does with its power, but how it explains it.
