Revitalizing U.S. Global Leadership: The Case for an Alliance-Based Approach to Frontier Domain Engagement

Insight from the Pitch 2020: A Competition of New Ideas


The U.S. alliance system currently lacks clear and future-oriented goals. As a result, the alliance system is struggling to justify its existence and form a coherent and unified strategy to shape the international order. Alliance disunity and strategic regression are glaring examples of a loss of U.S. international leadership.

To strengthen U.S. global leadership and competitiveness, the United States should take an alliance-based approach to frontier domains like outer space, the Arctic, and the deep seabed. The primary goals of engagement would be to ensure U.S. cognizance and awareness of developments in contested areas, prevent dominance of these domains by any one nation, and promote sustained U.S. norms and global engagement. Leadership and competitiveness require a future-oriented and values-driven strategy that is practical and achievable.

Frontier domains are contested environments and are expected to increase in competition due to growing economic, security, political, technological, and environmental importance. Frontier domain engagement and development also are often expensive—some technologies necessary for exploration and operation are cost or resource prohibitive for certain countries. Considering these realities, frontier domains provide both long-term opportunities for the United States to reassert its global leadership and competitiveness, as well as multiple avenues for the United States to strengthen and advance its alliance system in the following ways:

  1. The international community relies on systems and capabilities linked to frontier domains; this reliance is likely to increase due to a proliferation of planned government and commercial projects, with the United States and its allies projected to continue leading on this front.
  2. Given that frontier domains lack established and easily enforceable rules and norms for engagement, the United States has an opportunity to actively influence global rules and norms in these areas aligned with its values and ambitions—a key measure of global leadership and competitiveness.

Case Study: Envisioning a Unified Alliance-Based Approach to Space

Space—and more specifically cislunar space—represents a large and expansive frontier with numerous challenges that have considerable global impact on political, economic, security, and military considerations. Space is integral to the international system, whether the domain is being exploited for scientific advancement, commercial gain, defense planning and disaster management, or everyday use via mobile apps. Space power is effectively a force multiplier in the military sense and in all other sectors that are dependent on rapid communication and the transfer of information. Space is likely to continue to grow in importance as emerging technologies, such as 5G and the internet of things, are expected to rely on space-based systems.


The United States should focus on establishing a national vision for space. The vision should propose responsible and sustainable engagement and development of outer space, staying consistent with prior U.S. National Space Policy documents. Additionally, an alliance-based approach to space should lay the foundation to ensure space stability, shape the strategic environment, and cooperate with allies and partners—an objective and priorities noted in the June 2020 Defense Department Defense Space Strategy Summary. With the aforementioned in mind, the U.S. government should:

  • Clarify a national vision and strategy for space activities rooted in U.S. values. Referencing NASA’s May 2020 Artemis Accords and international space law, key values could include: the peaceful use of space; recognition of space as a strategic asset to humanity; maintaining space as secure, stable, and accessible; sustainable and responsible development and engagement in space; and the use of space to inspire and improve the lives of humanity.
  • Create a multilateral body that coordinates public, private, and academic stakeholders and experts from allied nations to better develop a unified vision and strategy for engagement in space. Initial key space allies would likely include Canada, Japan, the UK, the European Space Agency, and Australia. This multilateral body could be structurally similar to a combination of the Arctic Council (only including spacefaring allies) and the Combined Space Operation Center. This new body would train and promote close coordination and collaboration between allies on space policy, strategy, activities, and operations, particularly in terms of security cooperation (U.S. Space Force, Japan’s Space Operations Squadron, Canada’s Armed Forces Space Cadre, etc.).
  • Work with allies to develop a comprehensive approach to tackle pressing domain-specific issues. Some initial pressing challenges include developing guidelines to keep low Earth orbit as a renewable resource via active debris removal—an issue which the Inter-Agency Space Debris Coordination Committee mitigation guidelines lays a framework to work from. Guidelines for delineating how resource ownership will work in space and on foreign celestial bodies (the moon, Mars, etc.) should also be discussed. Easy areas of cooperation include crisis and disaster management efforts, and information sharing and collective development of space situational awareness capabilities.
  • Aim to balance the development of existing partner and non-ally space relationships with the development of new domain-specific relationships across key space agencies and defense forces. The United States should continue its cooperation with Russian space agency Roscosmos, despite concerns regarding greater global competition between the two nations. U.S.-allied space cooperation should focus on establishing rules and norms for domain engagement in order to allow for the development of space capabilities to continue to be competitive, while limiting the potential for heightened tensions with domain competitors. Additionally, the United States and allies should continue to work with developing spacefaring nations—particularly those who share U.S.-allied space values and goals.


Frontier domains present important opportunities for the United States and its allies in exploration, commercial engagement, and security consideration for the international community. It is crucial for the United States to define a clear and future-oriented vision with allies and partners to defend against potential conflict resulting from miscommunication or unchecked aggression. This will help ensure U.S. values are a core component of generations of exploration and engagement in progressively crucial domains.
