Congress has spent much of the past several years reacting to crises abroad after the fact. On Russia and Iran, it now has an opportunity to do something more useful: strengthen American leverage before events deteriorate further. That is why lawmakers should give serious support to the Russia and Iran sanctions legislation associated with Sen. Lindsey Graham and allied members of Congress.
The core case is straightforward. Russia continues its war against Ukraine, a conflict that has reshaped European security and tested the West's willingness to sustain a long contest of endurance. Iran, meanwhile, remains a central source of instability in the Middle East through its support for proxy groups, its missile and drone programs, and its broader challenge to the regional balance of power. These are not unrelated problems. They are part of a larger pattern in which revisionist states cooperate, trade technology, and exploit American hesitation.
Sanctions are not a magic wand. They do not replace military strength, diplomatic clarity, or a serious energy policy. But they remain one of the few tools available between speeches and war. Used properly, they can constrain hostile regimes, raise the cost of aggression, and signal that the United States still understands how to use economic power in defense of strategic interests.
Why Congress, Not Just the White House, Should Act
There is a tendency in modern Washington to assume that foreign policy belongs primarily to the executive branch. The Constitution says otherwise, and prudence does too. Congress has an important role in setting the legal architecture for sanctions, appropriating enforcement resources, and making clear to adversaries that American resolve does not vanish with the next personnel change in the administration.
A statute passed by Congress has advantages that an executive order does not. It is harder to unwind, more credible to allies, and more threatening to adversaries who might otherwise gamble that time is on their side. If the United States wants Moscow and Tehran to believe that pressure will persist, then Congress should put that pressure on a firmer footing.
This matters especially because both Russia and Iran have learned to wait out Western attention spans. They assume democracies tire, coalitions fray, and temporary measures lapse. A bipartisan sanctions law would tell them that, at least on this point, American institutions can still produce durable policy.
The Strategic Logic of Tougher Sanctions
Russia's war machine runs not only on ideology and repression, but on money, industrial capacity, and external procurement networks. Oil and commodity revenues, access to shipping and finance, and third-country channels for dual-use goods all help sustain the Kremlin's ability to continue the war. The purpose of sanctions should be to make that machine less efficient, more expensive, and more isolated.
Iran presents a related challenge. Its ability to fund proxies and arm partners depends in part on energy exports, sanctions evasion, and access to international markets through intermediaries. Tehran has become an exporter of instability, and that instability increasingly spills across regions. The United States has strong reasons to treat that as more than a local problem.
A serious sanctions bill should therefore aim at several targets at once:
- Revenue streams that finance military operations and proxy warfare.
- Shipping and insurance networks used to move sanctioned goods.
- Foreign financial institutions and intermediaries that knowingly facilitate evasion.
- Procurement channels for components with military or dual-use applications.
- Entities helping transfer weapons technology among hostile states.
The point is not symbolic punishment. It is to degrade state capacity where it matters most.
A Conservative Case for Economic Pressure
Some on the right are understandably skeptical of open-ended foreign commitments, and that skepticism is not irrational. The country has earned its weariness with missions that drift and policies that are never properly explained. But there is a large difference between prudence and passivity.
Conservatives should prefer the steady use of American economic and institutional strength over the false choice between doing nothing and sending troops. Sanctions, when tied to clear objectives and enforced seriously, are a middle instrument of power. They are compatible with realism because they recognize that hostile regimes respond to pressure. They are compatible with constitutional government because Congress can define their scope. And they are compatible with restraint because they seek to deter escalation rather than invite it.
There is also a broader principle here. The United States cannot preserve a stable international order if aggressive states conclude that commerce with the West can continue more or less normally while they wage war, arm proxies, or menace neighbors. Markets are not self-defending institutions. They depend on rules, credibility, and the willingness of governments to protect the conditions under which lawful trade can flourish.
The Limits of Sanctions Are Real
Supporters of stronger sanctions should be candid about the limits. Sanctions rarely produce instant capitulation. They can be undermined by weak enforcement, indifferent allies, or loopholes large enough to drive tankers through. They can also impose costs on global markets, especially in energy, if policymakers are careless.
That is an argument for better design, not surrender. Congress should pair sanctions authority with robust oversight of enforcement. It should demand regular reporting from the administration on evasion networks, licensing practices, and the conduct of foreign firms that help sanctioned states access capital or technology. It should also coordinate pressure with allies wherever possible, because sanctions work best when major economies move together.
At home, lawmakers should think seriously about the energy dimension. A country that wants to use energy sanctions effectively should also want abundant and reliable energy production among itself and its allies. Strategic seriousness abroad requires economic competence at home. It is difficult to squeeze petrostates if the free world has made itself needlessly fragile.
What Passage Would Signal
If Congress passes a strong Russia and Iran sanctions measure, the immediate effect will be practical: more legal authority, more pressure points, and more risk for the banks, shippers, traders, and middlemen who help these regimes blunt existing restrictions. But the larger effect would be political.
It would signal that the United States still knows how to connect means to ends. It would reassure allies that Washington has not simply accepted a world in which aggressors absorb penalties as a manageable cost of doing business. And it would remind adversaries that American power is not limited to military deployments and press conferences.
Washington often talks as though toughness consists mainly of rhetoric. In reality, toughness is institutional. It is the patient construction of laws, incentives, penalties, and enforcement mechanisms that shape behavior over time. Congress has a chance to do that here.
No sanctions bill will solve the Russia problem or the Iran problem by itself. But failing to tighten the pressure would amount to a familiar and costly mistake: allowing hostile regimes to assume that the United States is more comfortable expressing concern than imposing consequences. Congress should prove otherwise.
