At the time, the Soviet Union and United States committed to reducing their nuclear arsenals, eliminating an entire category of nuclear weapons, and allowing thorough onsite inspections to ensure treaty compliance. During the Cold War, the INF Treaty served as a crucial stabilizing mechanism in the global nuclear order. Historically, the Strategic Arms Limitation Talks (SALT) of 1972 and 1979 were the first of several agreements between the US and the Soviet Union. As a result, both sides agreed to reduce their strategic weaponry, which included ballistic missile defenses, submarine-launched ballistic missiles, and intercontinental ballistic missiles.

In 1987, Ronald Reagan and Mikhail Gorbachev signed the INF Treaty. Additionally, they established inspection procedures to make sure both parties followed the agreement. Due to the treaty, 2,600 missiles were destroyed, marking a significant Cold War breakthrough. Despite decades of arms control, the US and Russia still field the largest nuclear forces. Although it is challenging to determine the exact extent of their stockpiles, the Stockholm International Peace Research Institute (SIPRI) estimates that the US possesses 5,328 warheads, while Russia has 5,580.

In August 2025, Russia declared it would no longer fulfil its commitments under the INF Treaty, citing increasing threats from the United States and other Western nations. When the US withdrew from the INF Treaty in 2019 because of Russian noncompliance with treaty limitations, Moscow stated that it would not use such weapons as long as Washington did not. This may have served as an effective ruse, but it served a purpose.

Questions are increasing about the utility of nuclear proliferation, the threat of arms racing, and the future of nuclear deterrence following the decision of Russia to fully abrogate the INF Treaty. The collapse of the INF Treaty represents a significant shift in the trajectory of international arms control.

The situation took a more dramatic turn as President Donald Trump announced that the US would move two of its nuclear-armed submarines closer to Russia in reaction to the “inflammatory statements” issued by former Russian President Dmitry Medvedev. This action highlights the challenge that arises when arms control breaks down—the potential for misunderstandings and overreactions increase.

Among nuclear-armed states, communication, predictability, and a certain measure of self-control are essential elements of nuclear deterrence. They were shaped by the INF Treaty, which placed verifiable limitations on missile sites. With the failure of the INF Treaty, useful tools were removed.

The future deployment of intermediate-range systems in regions that were shielded from them may prove an urgent strategic issue. Once at the epicenter of Cold War nuclear worries, Europe may have to host such weapons once more, but with improved accuracy, shorter travel times, and, perhaps, lower yields.

Deterrence dynamics in the Asia-Pacific are more difficult, especially between the US, China, and Russia, after the INF Treaty. The great powers are now accelerating nuclear modernization, while non-nuclear states are reconsidering their nonproliferation commitments. A replay of the Cold War–era European missile crisis has emerged with the collapse of the treaty.

Now, both Russia and the US are free to use and develop short-, medium-, and intermediate-range missiles without any official restraints. One more issue concerns the intentions of other governments, who may be influenced by the deterioration of controls on nuclear systems. States that did not previously possess nuclear weapons may choose to acquire them. Modern arms racing may be fast, less predictable, and more destabilizing due to technological advancements, such as autonomous delivery systems, hypersonic weapons, and AI-assisted targeting.

There are limited prospects for cooperative tools to mitigate these risks of escalation between the US and Russia. The two largest nuclear powers have a special duty to control and limit the scope of their competition.

Measures that encourage openness, trust, and communication between nuclear and non-nuclear governments will be crucial. In the absence of a global treaty, regional security accords, tailored to today’s security challenges, can effectively restrict risky deployments and restrain great powers from further modernizing their nuclear arsenals.

Nations in the Asia-Pacific can, for example, agree to mutual missile deployment restrictions similar to those in the INF Treaty’s verification procedures, which include regular inspections and satellite monitoring by mutual compliance. This would prevent insecure military build-ups in the region and reduce mistrust between states. Whatever course nations take, the importance of preventing escalation to nuclear use is foremost.

However, there are at least two major areas of concern for an effective future USSF international strategy: divisive geopolitics in space and foundational issues of a real space defense strategy beyond support services. In addition to geopolitical and strategic quandaries, organizational politics stand in the way of a sound strategy.

Divisive Geopolitics

Europe acknowledges space as congested and contested but stops short of calling space a warfighting domain. Europe adamantly refuses to declare China as a threatening adversary in the space domain. Not only does Europe struggle with a China dependency, chasing elusive economic benefits, but mainstream European diplomacy emphasizes engagement with China as a preferred way to hedge against (allegedly) unpredictable American behavior.

China managed to deter Europe from taking any offensive space posture, further making sure the North Atlantic Treaty Organization (NATO) remains busy with relentless Russian threats. It remains unclear where Europe would stand in a collective space defense scenario resulting from a multi-theater conflict involving both Taiwan and Eastern Europe.

Strategic Quandary

The USSF international partnership strategy signals a service fixated on space support rather than getting after the real problem, which is defeating space threats. This cannot be achieved without offensive space capabilities that deter, and, if necessary, destroy enemy capabilities.

In Europe and the Indo-Pacific, France and Japan are technologically capable of developing offensive capabilities, but politics forbid them from fielding offensive weapons in space, leaving Russian and Chinese rendezvous and proximity operations and kill chains unchallenged. This means such partnerships are unlikely to support the US with truly offensive capabilities in space.

Effective Bilateral and Mini-lateral Partnerships

US Space Command shares space situational awareness data with 33 partner countries, including Australia, Canada, France, Japan, Norway, and the United Kingdom (UK). Multinational Force Operation Olympic Defender (OOD) is a US Space Command operation to strengthen defenses and deter aggression in space, and involves more than six countries.

US Space Command and the US Space Force have agreements for exchange of personnel and liaison officers for these countries. Bilateral and mini-lateral partnerships include hosting payloads on allied systems such as Norway’s Arctic Satellite Broadband Mission (ASBM) and Japan’s Quasi-Zenith Satellite System (QZSS aka Michibiki); Deep Space Advanced Radar Capability (DARC) with the UK and Australia; and Joint Commercial Operations (JCO) using commercial space domain awareness data with allies and partners. Such needed bilateral and mini-lateral agreements get more done and faster.

Challenging Multilateral Partnerships

Implementing wideband global satellite communications (WGS) to provide satellite communications (SATCOM) to NATO can be challenging when over twenty nations all want to have their own homegrown terminals that can use any nation’s SATCOM satellites. This is made worse by the NATO Communications and Information Agency imposing further rules.

Bottlenecks with extremely high frequency (EHF) communications for nuclear deterrence means all capitals want to have a chance to say yay or nay on who makes the decision and communicates through the EHF with allied command operations. Compared with bi- or mini-lateral agreements, multilateral partnerships are complicated to implement.

The GAO Report on Organizational Politics

An earlier report by the Government Accountability Office (GAO) found that the US Department of Defense (DoD) faces persistent challenges that impede its efforts to integrate allies and partners into space operations and activities by establishing joint goals. The unclassified version of the GAO report tackles organizational politics specifically.
The report identified that the DoD has several organizations that have overlapping roles and responsibilities for space-related security cooperation.

Several foreign government officials said that finding the appropriate DoD contact with whom to coordinate is difficult, resulting in confusion and missed opportunities. GAO found that USSF has not identified, analyzed, or responded to the risk of not filling positions within its service components, including space-related planning, information sharing, and security cooperation positions.

The USSF strategy acknowledges resource constraints: personnel, budget, and time are limited for all parties. Overclassification limits intelligence sharing and is a concern. Policy misalignment, lack of straightforward national policies, and interoperability risks hinder cooperation.

The USSF is already seeking $6 billion for its own unfunded priorities such as its nascent Military Network (MILNET) satellite constellation and various classified projects. Meanwhile, China appears eager to beat the USSF to the punch in space refueling. Hence the criticality of the USSF astroscale refueling deal. Europe and Japan remain in the process of developing elementary space-based surveillance and passive defense assets.

Should the US Go It Alone in Space?

Current USSF half-baked strategic and cooperation models, leadership alignment issues, capability gaps among allies, and inefficiencies in multilateral agreements are not helping the US to lead in solving allies’ collective space security quandaries, let alone guaranteeing the United States’ own homeland security. In a worst-case scenario, the US might need to be prepared to go it alone and add foreign capabilities as “nice to have.”

If the US has more robust space capabilities, partnering with the US is more attractive for allies. The ability to go it alone with the prospect of winning is what gains allies, many of whom will be sitting on the fence. Furthermore, allies of the US could be knocked out, one-by-one, by China and Russia in orbit, leaving the US to go it alone anyway.

If the USSF international partnerships strategy is to be relevant, the USSF needs to further evolve from support functions to offensive space warfare, which should form the backbone of any allied international counterspace capabilities. Ultimately, in space, as on Earth, one either leads, follows, or gets out of the way. The US is allowing itself to be paralyzed by committee, which is a sure-fire way to lose the war in space that already started.

Current challenges include the disparity in nuclear capabilities, with Russia’s projected 7,500 warheads and China’s rapid buildup to 3,500 by 2035. The U.S. TRIAD faces maintenance issues, necessitating immediate investments in updated systems to avoid strategic vulnerabilities. Recommendations highlight the need to accelerate programs like the Navy’s nuclear-armed cruise missile initiative, expand the B-21 bomber fleet, and consider additional Columbia-class submarines. These steps are presented as crucial to addressing the growing threats from adversaries while ensuring strategic balance.

The report underscores the urgency of modernizing the U.S. nuclear deterrent to sustain global power and uphold international credibility. Strategic insights from leaders like General McMaster and Secretary Frank Kendall advocate for overcoming budgetary constraints and reinforcing the defense industrial base. The document also highlights broader geopolitical concerns, such as the implications of Russia’s invasion of Ukraine and Iran’s nuclear ambitions, framing modernization as a central pillar of U.S. security policy.
