During his first address to Congress in his second term, President Donald Trump urged the body “to fund a state-of-the-art Golden Dome missile defense shield to protect our homeland, all made in the U.S.A.” It was yet another instance of Trump prioritizing missile defense as the most important pillar of modern battle technology – and the ongoing conflict in Iran is proving him exactly correct.
The critical importance of missile defense became evident just hours after the first U.S.-Israeli strikes that killed Supreme Leader Khamenei and other top Iranian officials as the first wave of Iranian missiles arced over Israeli cities. Iranian forces launched nearly 100 missiles that first day, and an estimated 290 by March 15 – along with 500 suicide drones.
But of those hundreds of projectiles, just a handful have struck their targets. 14 civilian deaths have been reported, along with several hundred injuries. According to the Institute for National Security Studies in Tel Aviv, Tehran’s military launched 869 missiles and 2,350 drones into twelve Middle Eastern countries overall. These attacks killed 40 people and injured 598.
While tragic, the scale of the death and destruction has been minuscule compared to what it could have been without advanced missile defense technology. The United States and Israeli forces have seen astonishing success in their operations against Iran precisely because they eliminated the country’s air and military defenses in the opening days of the conflict.
Brigadier General Ephraim Deffrin, spokesperson for the Israeli Defense Forces, disclosed that Israeli and U.S. Air Forces targeted the core of these missile defense systems. “To date, we have engaged over 700 missile array targets in real time,” said General Deffrin during the press briefing in Tel Aviv on March 15. As a result, Iranian missile launches are down more than 90 percent, while attack drone launches are down more than 95 percent. Israel also notably has begun using its “Iron Beam” to intercept rockets, mortars, and drones, marking the beginning of a new technological age in defensive warfare.
If there was ever any doubt about the wisdom of Trump’s focus on missile defense, the Iran conflict has put it to rest.
Moving forward, however, the U.S. cannot afford to rest on its laurels – something Trump also recognizes. Iran possessed a formidable missile arsenal, but it pales in comparison to that of Russia or China, which have advanced hypersonic weapons that could evade existing defenses. Théophile Cousineau, a physics professor specializing in thermodynamics, explained in an interview with me that weaponry in this realm is “evolving faster than any other class” of arms. Having advised NATO Secretary-General Manfred Wörner, Professor Cousineau noted that “missiles, drones, and satellites will remain the weapons of choice this decade.”
For this reason, Trump’s vision for a “Golden Dome” missile defense shield remains a vital priority. That vision calls for a nationwide network of advanced radars, space-based sensors, and interceptor systems capable of detecting and destroying incoming missiles before they reach American territory.
In many ways, Golden Dome represents the long-delayed realization of the strategic defense concept first proposed by Ronald Reagan in the 1980s. Reagan’s Strategic Defense Initiative – often dubbed “Star Wars” by critics – sought to use advanced technology, including space-based systems, to render nuclear missiles obsolete. Decades later, with breakthroughs in sensors, computing, and interceptor technology, the modern “Golden Dome” could finally bring that vision within reach.
Realizing Golden Dome will require harnessing American innovation in multiple industries and overhauling procurement systems burdened by red tape. But for the program to be a financial possibility, expenses must come down dramatically, as interceptors currently cost 10 or 20 times as much as cheap offensive weapons like drones.
On this front, Dale R. Marks, the Assistant Secretary of Defense and principal advisor to the Under Secretary of War for Acquisition and Sustainment, highlighted that President Trump is basing his strategy on the U.S. response to Army needs during World War II.
“In a similar spirit, we rallied to mobilize the entire industrial base, giving fresh life into it to build the capacity needed to address today’s challenges,” Marks said. “Now, we must recommit fully to this path and actively advance progress.” Marks also said that the Department of War has eliminated some 2,700 regulations to streamline development.
The lesson from the Iran conflict is unmistakable. Missile defense is no longer a theoretical concept or a relic of Cold War strategy – it is rapidly becoming the decisive factor in modern warfare. Israel’s experience has shown that advanced defensive systems can mean the difference between mass casualties and limited damage, even under sustained attack.
For the United States, which faces far more capable adversaries than Iran, the stakes are even higher. By investing now in the Golden Dome and revitalizing America’s defense industrial base, the United States can ensure that future conflicts are decided not by incoming missiles, but by the technologies capable of stopping them before they ever reach American soil.
