Are the Iran strikes a good idea?

“My proudest legacy will be that of a peacemaker and unifier,” President Trump announced in his second inaugural. “That’s what I want to be: a peacemaker and a unifier.”

By launching an unnecessary and illegal war against Iran, President Trump has forever undermined this goal. The Iranian regime is many things — evil, dictatorial, murderous, even dangerous. But it’s hardly an “imminent threat” justifying preventive war.

In fact, the Iranian regime is weaker today than it has been in decades. Its economy is in shambles due to decades of sanctions and mismanagement. Its proxies have been decimated by Israel in two years of unrelenting war. Its allies in Syria and elsewhere have been ousted. Its nuclear program was buried deep underground by the June 2025 Israeli-U.S. bombing campaign. Its missile stockpiles have dwindled, and its production facilities have been damaged. Its Air Force cannot fly, its Army cannot move beyond its borders, and its Navy is little more than a coastal fleet.

The strikes may have killed the Supreme Leader. But that alone will not end the regime or free the Iranian people. Instead, the country and region will be left in chaos on ruins — with the United States now bearing responsibility for their future.

The Iran strikes are extraordinarily risky and carry a high degree of uncertainty especially when considering second and third order effects. By opting for the most ambitious set of objectives centered on regime change along with destroying Iran’s nuclear, ballistic missile and military capabilities, the Trump administration has set a high bar for what can only be described as a war of choice, not necessity. Iran’s capabilities are certainly eroded, but given the existential stakes, Tehran has already demonstrated its willingness to lash out recklessly, regardless of the consequences. If Iran is going down, it will seek to take others with it. It will subject the region to destabilizing retaliation, potentially striking energy infrastructure and other economic targets and possibly impeding traffic through the Strait of Hormuz with significant impacts on oil prices. The Iran strikes may prove to be a costly gamble by the United States — not a good thing.

The Iranian regime is responsible for the deaths of many hundreds of Americans. The regime’s rallying cry is “Death to America.” It attacks and undermines U.S. allies across the Middle East, from Saudi Arabia to Bahrain to Jordan to Israel, while seeking to develop missile and nuclear capabilities that threaten the United States. President Trump’s decision to launch Operation Epic Fury, in partnership with Israel, will go down in history not only as a good idea, but as one of the most consequential decisions in military history.

Iran is not Iraq or Afghanistan. It has a highly educated opposition dedicated to building an open, democratic and moderate future. If the U.S. and Israel stay the course and create the conditions for the ayatollahs’ downfall, this would be a major blow to Iran’s entire axis of terror, and a major step forward in shaping a stable, secure and prosperous Middle East.

We have neither a clear objective nor a post-war plan for success. Without these two critical elements, we have made the calculation that the unknown is better than the status quo. The known included the ongoing negotiations with Iran, a reasonable assessment of its uranium production, a detailed, proven understanding of its leadership’s mindset and likely actions, and necessary intel about the regime’s Achilles heels. In short, our knowledge was deep, clear and steady. With the assassination of Khamenei (who was very old and sick anyway and could have died at any time), we have a strategic knowledge deficit. Should the regime last, we do not know how new leaders will lead, assess, respond. Should the regime collapse completely, we are betting things will go our way or, worse, imagining and hoping that they will. Hope is not a strategy as we have learned the hard way — and we have rarely imagined the follow-on effects of things we set in motion with regime change (e.g., Iraq, Afghanistan, Libya).

Which brings us to soft power. To pick the timing of a military attack (hard power) on one’s enemy is a luxury. Under such circumstances, one would naturally expect a well-thought-through, multi-pronged plan for a soft-power war alongside it. Once the air attacks stop, what will be happening on the ground? Have lessons from the Arab Spring been learned? Does the administration believe that the youth, who are unarmed, will have the power to build a new Iran and defeat those who still have weapons? Do we believe that bad actors will not be working to reset the nation ideologically? The truth is we do not have any idea how the vacuum will be filled and we almost certainly have not done the necessary work to give all the anticipated scenarios the best chance of landing where we need them to. With the administration having decimated America’s usual levers of soft power like USAID, what is the plan to influence the emotions of the people, or even a method to bring new leaders who will be favorable to America’s bottom line? Sen. Lindsey Graham has been sporting a hat that reads “MAKE IRAN GREAT AGAIN.” Time will tell if the slogan inspires a new, better chapter or, more likely, disintegrates like his cheap-looking hat.

Donald Trump promised in his 2025 inauguration speech that the success of his presidency would be measured “perhaps most importantly [by] the wars we never get into.” Yet the self-styled “President of Peace” has managed, in just over a year, to wage military conflicts in at least seven countries, including Iran.

These attacks are badly misguided. (Some literally so: Early reports suggest that U.S. strikes have, among other things, mistakenly hit a girls’ elementary school, killing scores of children.) Most fundamentally, they violate international law: Iran posed no imminent threat to the United States. Don’t care about that? These strikes also violate U.S. law. The Constitution gives Congress — not the president — the power to declare war, and Congress never authorized this use of force.

In addition, the strikes epitomize strategic folly. As Trump himself observed in 2016, “Our current strategy of nation-building and regime-change is a proven, absolute failure.” You can kill or kidnap a nation’s repressive leaders, but you cannot democratize or stabilize a country of 90 million people with airstrikes alone. Far more likely, the attack will further destabilize an already volatile region, putting U.S. service members, American allies and global shipping, trade and energy supplies at risk — while endangering millions of civilians in Iran and beyond.

Most troubling, the Iran strikes cement a pattern that was already becoming clear. After the U.S. attack on Venezuela and threats directed at Greenland, the territory of a NATO ally, the United States increasingly resembles the very kind of rogue state it once condemned. A nuclear superpower that places itself above law, loyalty, facts and prudence invites a dangerous reframing: Other nations may begin to view the United States the same way international law has traditionally viewed pirates — as hostis humani generis, the enemy of all mankind.
