This piece argues that America has lived in wartime since World War II, that Iran has been a persistent enemy, and that President Donald Trump restored ruthless realism to U.S. policy—tearing up the “JCPOA,” striking where needed, and ordering operations that crippled Iran’s nuclear and missile capabilities. It contrasts earlier presidents’ failures or hesitations with the decisive approach taken after 2017, and it presses the case that staying tough is the route to a lasting deterrent.
Americans have known conflict for generations, and every modern president has been judged by how they handle both “cold” and “hot” wars. There were long stretches that felt like “peacetime,” but those intervals were often illusions, followed by reminders that bad actors never go away. Recognizing that reality matters because deterrence depends on consistency and resolve.
Iran has been an adversary since the 1979 hostage crisis and has repeatedly targeted American lives and interests overseas. From the Marine barracks bombing to the Khobar Towers attack and the long campaign against U.S. forces in Iraq, Tehran backed proxies and kept a chant alive: “Death to America.” That hostility has always been explicit and long-term.
Too many administrations promised to stop Iran’s march toward a bomb but failed to act decisively. Presidents from Carter to Obama hesitated, miscalculated, or tried appeasement instead of pressure, and the result was an emboldened regime working on both nuclear capability and an expanding missile force. When policymakers accept costs over confronting threats, adversaries read that as opportunity.
President Trump changed that posture by reviving blunt, unapologetic tools of statecraft and force. He tore up the “JCPOA” and reasserted a red line that had been softened by prior leaders, including the famous “Red Line” moment that became a cautionary example. Tactical strikes, targeted decapitation of terrorist leaders, and clear consequences shifted Tehran’s calculation.
When Iranian proxies attacked Americans in Iraq and when Qassem Soleimani directed lethal campaigns, Trump ordered decisive action. The killing of Soleimani in January 2020 was controversial, but it signaled a return to accountability for attacks on U.S. personnel. Those moves were part of a broader campaign that combined military pressure with sanctions and diplomatic isolation.
Later operations intensified that pressure. Reports describe operations like Operation Midnight Hammer that struck hard at Iran’s nuclear infrastructure, and follow-up strikes that degraded missile factories and military production lines. Taken together, these actions aimed to remove Tehran’s ability to field a credible nuclear assembly line and to blunt its missile stockpiles.
Critics warned of blowback, but hard power also creates bargaining leverage and buys time for allies. Trump’s approach restored deterrence in a way that diplomatic niceties alone had not. By degrading Iran’s capacity to wage proxy wars and to produce deliverable nukes, the aim was to prevent a regional arms race and to protect Israel, Gulf partners, and U.S. forces.
The Biden era that followed saw confusion and setbacks in other theaters that eroded confidence in American will, and those weaknesses encouraged rivals. Abandoning standards in one place invites aggression in others, and a pattern of retreat invites adversaries to test limits. For supporters of a robust foreign policy, the lesson is simple: firmness, not appeasement, preserves peace.
Now the question is whether that firmness can be maintained long enough to produce a generational deterrent. The campaign against Iran’s nuclear and missile infrastructure has already set Tehran back and raised the costs of rebuilding. If policymakers remain determined and ruthless where necessary, the United States can blunt Tehran’s ambitions and make the region safer for years to come.
