Yves right here. It’s arduous to say sufficient dangerous issues about Trump’s Golden Dome pork mission. Haig Hovaness had a go, however there may be vastly extra so as to add, as this publish demonstrates.

President Donald Trump’s concept of a “Golden Dome” missile protection system carries a spread of potential strategic risks for the US.
Golden Dome is supposed to guard the U.S. from ballistic, cruise and hypersonic missiles, and missiles launched from area. Trump has referred to as for the missile protection to be absolutely operational earlier than the tip of his time period in three years.
Trump’s objectives for Golden Dome are seemingly past attain. A variety of research makes clear that even defenses way more restricted than what Trump envisions can be far costlier and fewer efficient than Trump expects, particularly in opposition to enemy missiles outfitted with fashionable countermeasures. Countermeasures embody a number of warheads per missile, decoy warheads and warheads that may maneuver or are tough to trace, amongst others.
No matter Golden Dome’s feasibility, there’s a lengthy historical past of scholarship about strategic missile defenses, and the load of proof factors to the defenses making their host nation much less secure from nuclear assault.
I’m a nationwide safety and overseas coverage professor at Harvard College, the place I lead “Managing the Atom,” the college’s predominant analysis group on nuclear weapons and nuclear power insurance policies. For many years, I’ve been collaborating in dialogues with Russian and Chinese language nuclear specialists – and their fears about U.S. missile defenses have been a constant theme all through.
Russian President Vladmir Putin and Chinese language chief Xi Jinping have already warned that Golden Dome is destabilizing. Together with U.S. offensive capabilities, Golden Dome poses a risk of “instantly undermining world strategic stability, spurring an arms race and rising battle potential each amongst nuclear-weapon states and within the worldwide enviornment as an entire,” a joint assertion from China and Russia stated. Whereas that could be a propaganda assertion, it displays actual issues broadly held in each international locations.
Golden Dome defined.
Historical past Classes
Expertise going again half a century makes clear that if the administration pursues Golden Dome, it’s prone to provoke even bigger arms buildups, derail already-dim prospects for any negotiated nuclear arms restraint, and maybe even improve the probabilities of nuclear warfare.
My first e-book, 35 years in the past, made the case that it will be within the U.S. nationwide safety curiosity to stay inside the 1972 Anti-Ballistic Missile Treaty, which strictly restricted U.S. and Soviet – and later Russian – missile defenses. The USA and the Soviet Union negotiated the ABM Treaty as a part of SALT I, the primary agreements limiting the nuclear arms race. It was permitted within the Senate 98-2.
The ABM Treaty expertise is instructive for the implications of Golden Dome at the moment.
Why did the 2 international locations comply with restrict defenses? In the beginning, as a result of they understood that until all sides’s defenses had been restricted, they might not have the ability to cease an offensive nuclear arms race. If all sides needs to take care of the flexibility to retaliate if the opposite assaults – “don’t nuke me, or I’ll nuke you” – then an apparent reply to 1 aspect build up extra defenses is for the opposite to construct up extra nuclear warheads.
For instance, within the Sixties and Seventies, the Soviets put in 100 interceptors to defend Moscow – so the US focused nonetheless extra warheads on Moscow to overwhelm the protection. Had it ever come to a nuclear warfare, Moscow would have been much more totally obliterated than if there had been no protection in any respect. Either side got here to comprehend that limitless missile defenses would simply imply extra offense on either side, leaving each much less safe than earlier than.
As well as, nations seen an adversary’s protect as going hand in hand with a nuclear sword. A nuclear first strike may destroy a significant a part of a rustic’s nuclear forces. Missile defenses would inevitably be simpler in opposition to the lowered, disorganized retaliation that they knew can be coming than they might be in opposition to a large, well-planned shock assault. That potential benefit to whoever struck first may make nuclear crises much more harmful.
Publish-ABM Treaty World
Sadly, President George W. Bush pulled the US out of the ABM Treaty in 2002, searching for to free U.S. improvement of defenses in opposition to potential missile assaults from small states corresponding to North Korea. However even now, a long time later, the U.S. has fewer missile interceptors deployed (44) than the treaty permitted (100).
The U.S. pullout didn’t result in a right away arms buildup or the tip of nuclear arms management. However Putin has complained bitterly about U.S. missile defenses and the U.S. refusal to just accept any limitation in any respect on them. He views the U.S. stance as an effort to attain army superiority by negating Russia’s nuclear deterrent.
Russia is investing closely in new sorts of strategic nuclear weapons supposed to keep away from U.S. missile defenses, from an intercontinental nuclear torpedo to a missile that may go around the globe and assault from the south, whereas U.S. defenses are primarily pointed north towards Russia.
Equally, a lot of China’s nuclear buildup seems to be pushed by wanting a dependable nuclear deterrent within the face of the US’ functionality to strike its nuclear forces and use missile defenses to mop up the rest. Certainly, China was so angered by South Korea’s deployment of U.S.-provided regional defenses – which they noticed as aiding the U.S. capacity to intercept their missiles – that they imposed stiff sanctions on South Korea.
Now, Trump needs to go a lot additional, with a protection “without end ending the missile risk to the American homeland,” with successful fee “very near 100%.” I imagine that this effort is very prone to result in nonetheless bigger nuclear buildups in Russia and China. The Putin-Xi joint assertion pledges to “counter” defenses “aimed toward reaching army superiority.”
Given the benefit of creating countermeasures which are terribly tough for defenses to beat, odds are the ensuing offense-defense competitors will depart the US worse off than earlier than – and a very good bit poorer.
Putin and Xi made clear that they’re notably involved concerning the hundreds of space-based interceptors Trump envisions. These interceptors are designed to hit missiles whereas their rockets are nonetheless burning throughout launch.
Most international locations are prone to oppose the concept of deploying enormous numbers of weapons in area – and these interceptors can be each costly and susceptible. China and Russia may deal with additional creating anti-satellite weapons to blow a gap within the protection, rising the chance of area warfare.
Already, there’s a actual hazard that the entire effort of negotiated limits to mood nuclear arms racing could also be coming to an finish. The final remaining treaty limiting U.S. and Russian nuclear forces, the New START Treaty, expires in February 2026. China’s speedy nuclear buildup is making many protection officers and specialists in Washington name for a U.S. buildup in response.
Intense hostility throughout signifies that for now, neither Russia nor China is even prepared to sit down down to debate nuclear restraints, in treaty kind or in any other case.
For my part, including Golden Dome to this flamable combine would seemingly finish any prospect of avoiding a way forward for unrestrained and unpredictable nuclear arms competitors. However paths away from these risks can be found.
It might be fairly believable to design defenses that would supply some safety in opposition to assaults from a handful of missiles from North Korea or others that might not significantly threaten Russian or Chinese language deterrent forces – and design restraints that might permit all events to plan their offensive forces understanding what missile defenses they might be dealing with within the years to come back.
I imagine that Trump ought to mood his Golden Dome ambitions to attain his different dream – of negotiating a deal to cut back nuclear risks.
