As a former deputy commander of U.S. Central Command, a Navy SEAL and a member of the National Security Council under former President George W. Bush, I spent decades helping oversee U.S. military operations across the Middle East under leaders including Jim Mattis and Lloyd Austin, both of whom later served this nation as Defense secretary. If I were advising President Donald Trump now, my message would be simple: Do not confuse a pause in hostilities with Iran — or even a limited, chaotic “opening” of the Strait of Hormuz — with a durable solution to the hostility between our nations.
The president’s position on Iran has, at times, appeared inconsistent.
The president’s position on Iran has, at times, appeared inconsistent. At times, he has suggested regime change in Iran as an objective. At others, his focus has shifted toward more limited goals, such as preventing a nuclear weapon, reopening the Strait of Hormuz or securing concessions through negotiation. Those are important objectives but they are not, by themselves, a strategy for ending the threat posed by the regime in Tehran. A lasting resolution requires a clearly defined end state.
That kind of clarity has been missing in how the United States has communicated its objectives. Statements suggesting overwhelming or immediate destruction may project strength, but they can also create ambiguity about U.S. intent. Deterrence works best when it’s consistent and tied to clear strategic objectives.
That starts with being clear about the threat. Iran’s leadership has consistently pursued nuclear capability, advanced its missile program, expanded proxy networks across the region and actively supported U.S. adversaries. Those are still their goals, and those goals are not going away. Iran will continue pursuing them regardless of temporary pauses or agreements.
For nearly five decades, U.S. policy has focused on slowing Iran’s progress rather than stopping it outright. Sanctions, limited strikes and negotiated agreements have each had moments of success. But nothing yet has altered the regime’s direction. Instead, our actions have bought more time for Iran to rebuild and continue advancing under less immediate pressure. The current ceasefire fits that pattern. It will lower tensions in the short term, but it will not resolve the underlying conflict.
That raises a more fundamental question: What is the objective? If the goal is simply to manage the threat, then another ceasefire and another round of negotiations may suffice. But if the goal is a lasting resolution, then the U.S. must be clear about what that requires. As long as the current regime remains in power, Iran will continue pursuing the same policies it has for decades. That’s why regime change is not a secondary objective; it is the only path to a durable resolution.
But that does not mean a U.S. invasion of Iran. It means pursuing a different strategy: one that applies sustained economic and operational pressure to the regime’s core institutions, including measures such as targeted economic and maritime restrictions, one that sets clear and enforceable conditions in any negotiation and creates the conditions for internal change over time.
Iran’s nuclear infrastructure must be fully dismantled. Its stockpile of highly enriched uranium must be removed.
First, any negotiation must be anchored in non-negotiable outcomes. Iran’s nuclear infrastructure must be fully dismantled. Its stockpile of highly enriched uranium must be removed. Support for proxy militias and terrorist networks must end. The free flow of commerce through critical waterways such as the Strait of Hormuz must be guaranteed.
Second, pressure must extend beyond military targets to the core structures that sustain the regime’s power. That includes the Islamic Revolutionary Guard Corps, its financial networks and the internal security apparatus that enforces control at home.
Third, the U.S. should more clearly support Iranians. If regime change is to occur, then it will ultimately be driven from within. American policy can influence the conditions under which that change becomes possible: through information access, economic pressure and coordinated international isolation of the regime’s leadership.
The events of the past several weeks have already shifted the landscape. Iran’s leadership is under greater strain, its capabilities have been tested and its vulnerabilities are more visible than they have been in years. This is not a moment to reset the status quo on a regime that’s now operating from a weaker and more exposed position.
Trump was right to act on the threat Iran poses. But a ceasefire without a clearly defined political objective risks turning military gains into another temporary pause in a decades-long cycle. If the U.S. wants something more than a moment of calm, then it must be willing to define and pursue a different outcome.
There can be no lasting peace with the current regime in Tehran, which is why the current blockade is a step in the right direction. By applying sustained economic pressure without causing further destruction, or making sweeping financial concessions to Iran, it weakens the regime from within and moves us closer to the only outcome that can deliver lasting stability and peace.
