Trump's "Golden Dome" Shield - Watch the full documentary | ARTE in English - Arte.tv

Donald Trump is once again promoting his plan to build a "Golden Dome" missile defense system for the United States, a proposal that defense experts have repeatedly dismissed as technologically unfeasible and strategically misguided.

According to a new documentary from ARTE, Trump wants to replicate Israel's Iron Dome system on a continental scale to protect America from missile attacks. There's just one problem: the comparison makes no sense.

Israel's Iron Dome defends a country roughly the size of New Jersey from short-range rockets fired from Gaza and Lebanon. The United States spans 3.8 million square miles and faces entirely different threat scenarios. Scaling up a system designed to intercept crude rockets over a few dozen miles to cover an entire continent against intercontinental ballistic missiles is not just expensive -- it's a fundamental misunderstanding of how missile defense works.

A Shield That Can't Protect What It Claims To

The Iron Dome intercepts short-range threats traveling relatively slowly at low altitudes. ICBMs from adversaries like Russia or China travel at speeds exceeding 15,000 miles per hour and re-enter the atmosphere from space. They are fundamentally different threats requiring fundamentally different defensive systems.

The United States already operates the Ground-based Midcourse Defense system, which is designed specifically for ICBM threats. That system has cost over $40 billion since 2002 and has a spotty test record. Experts estimate that expanding it to provide comprehensive coverage would cost hundreds of billions more -- and still wouldn't guarantee protection against a sophisticated attack using decoys and multiple warheads.

Trump's "Golden Dome" appears to be less a serious defense proposal and more a branding exercise that conflates Israel's tactical success with American strategic needs.

Follow the Money

The documentary notes that the "Golden Dome" would prove "very expensive" -- a polite understatement. Defense contractors have been lobbying for expanded missile defense spending for decades, and Trump's proposal would open a new spigot of taxpayer dollars flowing to companies like Raytheon, Lockheed Martin, and Northrop Grumman.

Israel's Iron Dome system was developed with substantial American financial and technical support. U.S. taxpayers have already spent over $3 billion helping Israel build and maintain the system. Now Trump wants Americans to pay again to build a version that won't actually work for U.S. defense needs.

This follows a familiar pattern from Trump's first term: propose a flashy, expensive project with a catchy name, ignore expert advice about feasibility, and let connected contractors cash in while the public foots the bill.

What America Actually Needs

The real threats to American security are not the ones a "Golden Dome" would address. Cyberattacks, election interference, domestic terrorism, and climate-driven instability pose far more immediate dangers than a hypothetical ICBM strike.

Even within missile defense, experts argue that investing in diplomacy, arms control, and early-warning systems provides better security per dollar than attempting to build an impenetrable shield. The latter is not only prohibitively expensive but also destabilizing -- it encourages adversaries to build more and better offensive weapons to overwhelm any defense.

Trump's proposal ignores these realities in favor of a simple, appealing narrative: America will have the biggest, most beautiful missile shield, just like Israel but better. It's the same approach he took to the border wall -- a concrete (or in this case, electronic) monument to the illusion of total security.

The Cost of Magical Thinking

The ARTE documentary highlights how Trump's "Golden Dome" could prove very expensive. That's the understatement of the year. We're talking about a system that would cost hundreds of billions to build, tens of billions annually to maintain, and would still leave the country vulnerable to the threats it claims to address.

Meanwhile, that money could fund healthcare, infrastructure, education, or actual evidence-based security measures. But those don't come with a gold-plated brand name or the promise of an impenetrable shield against all threats.

Trump's "Golden Dome" is a fantasy dressed up as policy -- expensive, ineffective, and designed more to enrich defense contractors than to protect American lives. The only thing golden about it is the payday for the companies that would build it.
