President Trump has signed an executive order to develop a nationwide air defense system, which the White House has dubbed the “Iron Dome for America.” The order calls for a next-generation shield capable of defending against ballistic, hypersonic and cruise missile threats from adversaries like Russia, China and North Korea.
While the plan signals a renewed focus on homeland security, it also raises significant questions about cost, feasibility and implementation. Trump has directed Secretary of Defense Pete Hegseth to submit an implementation strategy within 60 days, but no budget estimates or timelines have been released.
How has the initiative been received?
Tom Karako, director of the Missile Defense Project at the Center for Strategic and International Studies, acknowledged the importance of prioritizing missile defense.
“The end here is that there is [a] gratifying prioritization of the problem. So that’s good,” he said. “It deserves to be a White House priority.”
Some lawmakers have praised the move:
“I’m thrilled to see President Trump prioritize the modernization and expansion of U.S. missile defense,” said Rep. Mike Rogers, chair of the House Armed Services Committee. “President Trump’s order makes it clear our missile defenses will be oriented to defend against all threats from peer, near-peer and rogue adversaries.”
International collaboration and advancing technology
The order also calls for increased collaboration with allies, enhanced protection for forward-deployed U.S. troops, and a review of strategic missile threats to the U.S. Trump wants a specific plan for defending against nuclear adversaries, including new funding proposals for the fiscal 2026 budget.
A key part of the initiative is the exploration of advanced technologies such as space-based interceptors, directed energy weapons like high-powered lasers and expanded ground-based interceptor (GBI) sites. While the U.S. currently maintains 44 GBIs across Fort Greely, Alaska and Vandenberg Space Force Base in California, it remains unclear how Trump intends to modernize or expand these defenses.
Trump’s campaign promise to build “the greatest dome of them all” has drawn comparisons to Israel’s Iron Dome, which is designed to intercept short-range rockets. However, the U.S. faces vastly different threats, requiring a layered missile defense system across land, sea and space.
Robert Soofer, head of the nuclear strategy project at the Atlantic Council, has advocated for such an approach.
“The missile threat to the homeland is real and growing and, if left unaddressed, could seriously undermine U.S. grand strategy and the very basis of national defense strategy,” he wrote in a recent report.
While many experts support upgrading missile defense, some warn that a large-scale expansion could fuel an arms race. Rep. Seth Moulton has expressed concern about the long-term impact.
“We are already in an arms race. Will it make our world more safe?” he asked in a 2023 congressional hearing.
Despite these uncertainties, Trump remains confident in the plan:
“We protect other countries, but we don’t protect ourself,” he said at the House GOP retreat. “The United States is entitled to that.”
