First, SDI was not an actual defense initiative as much as it was a response to the Soviet Union’s rapidly growing strategic nuclear offensive forces and their own anti-satellite space forces. As William Van Cleave wrote in his 1986 report,

The Soviet Union has long been developing a multifaceted ballistic missile defense and, in fact, has already begun deploying such a defense. The Soviets have also began exploiting space for military purposes nearly two decades ago. They have already deployed anti-satellite (ASAT) space weapons. The overriding threat to American security today—that is, a rapid growth in offensive nuclear and conventional weapons systems—has come about precisely because the Soviet Union has been racing to build a weapons system, while the United States has not.

The same can be said of China today and is true of Golden Dome.

While there are plenty of Chinese, Russian, and Western arms control advocates criticizing Golden Dome as weaponization of space and an imbalance of forces, they all fail to note that Golden Dome is a response to the current imbalance of nuclear and space forces that advantages China and Russia. The utility of nuclear weapons, coupled with the advancement of hypersonic and space-to-ground attack options in the hands of the nation’s enemies grew in recent years.

The Chinese are in the midst of a breakout in the size and capability of their nuclear forces. Both China and Russia are engaging in a similar effort with their space attack forces. Both deployed ASAT and other space weapons systems that not only threaten American critical space infrastructure, but the homeland itself. As such, Golden Dome is a response to the already de-stabilizing activities of the Chinese and Russians. They, not the United States, are actively building weapons systems, especially in space.

Second, the narrative that SDI was a weapons development program is false. President Reagan’s speech directing SDI called it a research or “study” program. The 1985 Report to Congress on the Strategic Defense Initiative said that “it should be stressed that SDI is a research program that seeks to provide the technical knowledge required to support a decision on whether to develop and later deploy advanced defensive systems. It is not a program to deploy those weapons.”

President Trump understands this by his comments that while Reagan pursued SDI, “[he] didn’t have the technology.” However, Golden Dome is, in fact, a weapons deployment program. As his directive in the executive order states, “The United States will provide for the common defense of its citizens and the nation by deploying and maintaining a next-generation missile defense shield…[including] the development and deployment of proliferated space-based interceptors capable of boost-phase intercept,” among other sensors, trackers, and other weapons capable of defeating various threats from hypersonic, ballistic, and cruise missiles. While SDI was a study for a future decision to deploy space-based missile defenses, Golden Dome is the decision to deploy before Trump leaves office.

Finally, another false narrative in the anti–Golden Dome commentaries is that the system will be full of “untested technology.” This is not the case. If anyone looks at the systems listed in the executive order from January 2025, one will see that several of the sensors and layers are already in the current programs of record, many of which have already started deployment in orbit.

While some of the systems, such as the space-based interceptor, are not deployed yet, the technology for intercepting such missiles is in various forms of testing and/or use—for decades. Just because SDI had grand visions of lasers bouncing off mirrors or large chemical lasers in space, does not mean that Golden Dome’s space-based interceptors must be based on those concepts. Current anti-ballistic missile tech gained considerable ground over the past four decades and is ready for deployment sooner than later.

Vulnerability is not an option. Protecting Americans and the homeland from space and missile attack is a strategic imperative that must not fail. Congress must ignore the false narratives of the late 20th century. The threat is real, the technology is real. It is time to field Golden Dome for America.

This important agreement, which places limits on strategic nuclear arsenals and provides verification mechanisms, may face an uncertain future under Trump’s leadership. During his first term, President Trump demonstrated a dislike of arms control, a trend that could seriously undermine multilateral efforts in maintaining global strategic stability.

 Trump’s Arms Control Record

 During Trump’s first term, the United States withdrew from the Intermediate-Range Nuclear Forces (INF) Treaty, a landmark agreement with Russia that had eliminated an entire class of nuclear weapons. While the US cited Russian violations of the treaty as the reason for American withdrawal, the move is concerning for European security and removes a crucial safeguard against nuclear escalation.

Trump also expressed skepticism toward extending New START, instead demanding the inclusion of China in future agreements. While China is increasing its nuclear capabilities, its nuclear arsenal remains smaller than the American and Russian arsenals. Trump’s insistence on China’s inclusion delayed negotiations, nearly causing the treaty to lapse even before the Biden administration secured its five-year extension.

These actions reflect a broader pattern of undermining multilateral arms control frameworks. Trump’s transactional approach prioritizes American advantage over long-term global stability, raising concerns about the future of arms control agreements under his leadership. Given his resounding victory in the recent election, the American people support his “America first” agenda, which will embolden Trump’s efforts to pursue his approach further.

 The Risks of Unilateralism

 Arms control agreements like New START, the Nuclear Non-Proliferation Treaty (NPT), and the now-defunct INF Treaty historically relied on multilateral cooperation to reduce the risks of nuclear conflict. These agreements were/are built on principles of mutual trust, verification, and a shared commitment to minimizing the threat of nuclear escalation. Russia’s suspension of New START and increasing US-China and US-North Korea tensions further empower Trump’s unilateralism. Taken together, the already fragile architecture of global arms control is likely to fracture.

If Trump allows New START to expire or pursues a renegotiation on his terms, the consequences could be severe, with both openly increasing their strategic nuclear forces.

A Fragmented Global Landscape

 The dissolution of New START would not only impact Russo-American relations but also have negative implications for global security. European NATO member states are, however, more concerned about the credibility of NATO’s nuclear deterrent. The bigger threat is Trump’s withdrawal from NATO, which could spur NATO member-states to expand their own arsenals in nuclear-sharing arrangements, while others might consider developing independent nuclear capabilities. This fragmentation could destabilize the transatlantic alliance and further weaken the global arms control regime.

Beyond Europe, arms control agreements are importantly observed by all states. In the Middle East, where tensions are already high, countries like Iran countries might accelerate its nuclear program. Similarly, North Korea may interpret American instability in arms control as an opportunity to modernize its arsenal.

Emerging Technologies and Strategic Instability

The erosion of multilateralism in arms control is compounded by the rise of emerging technologies such as hypersonic missiles, artificial intelligence, and cyber warfare. These advancements could transform the nature of modern conflict, introducing new challenges that traditional arms control frameworks are ill-equipped to address.

Under Trump’s leadership, the US is likely to prioritize investments in these technologies, potentially at the expense of traditional arms control efforts. For example, Trump’s first term emphasized missile defense systems, which Russia perceives as destabilizing. In response, Moscow invested heavily in countermeasures like hypersonic weapons. The potential weaponization of space and advancements in cyber capabilities further complicates the strategic landscape, creating new risks of miscalculation and escalation.

Lessons from History and the Importance of Multilateralism in Arms Control

The history of arms control offers valuable lessons about the importance of cooperation. Agreements like the INF Treaty and the Anti-Ballistic Missile Treaty were not merely symbolic but played critical roles in reducing nuclear risks during the Cold War. These treaties demonstrated that even adversaries could find common ground in the pursuit of mutual stability.

To mitigate risks, the international community must reaffirm its commitment to multilateral arms control. Organizations like the United Nations and NATO have a critical role to play in facilitating dialogue and promoting transparency. Only through a renewed commitment to multilateralism can the world hope to navigate the complex challenges of the 21st century and maintain global stability in the face of evolving threats.
