Since entering office, President Trump has taken steps to restructure the U.S. military to raise the profile of both its cybersecurity and space capabilities. The administration has elevated U.S. Cyber Command to a Unified Combatant Command and has implemented policies signaling a shift toward a more offensive cybersecurity mindset. The administration has also begun the process of establishing a U.S. Space Command, as well as pursuing a plan to create a new branch of the military centered around space-related operations. Although this restructuring does not by itself implicate international law, it might do so if it results in operational changes.

Since entering office, President Trump has taken steps to restructure the U.S. military to raise the profile of both its cybersecurity and space capabilities. The administration has elevated U.S. Cyber Command to a Unified Combatant Command and has implemented policies signaling a shift toward a more offensive cybersecurity mindset. The administration has also begun the process of establishing a U.S. Space Command, as well as pursuing a plan to create a new branch of the military centered around space-related operations. Although this restructuring does not by itself implicate international law, it might do so if it results in operational changes.

On August 18, 2017, President Trump released a presidential memorandum directing the secretary of defense to establish U.S. Cyber Command as a Unified Combatant Command.Footnote 1 Unified Combatant Commands are unified across the different military service departments—Army, Navy, and Air Force—but are divided up either by geographic region or by function.Footnote 2 Each “has a particular mission, and each may be involved in various operations or exercises.”Footnote 3 A long-standing congressional statute authorizes the president to create new Unified Combatant Commands and revise existing ones.Footnote 4 One of these existing commands—U.S. Strategic Command—had housed Cyber Command as a subordinate unit since its creation in 2010.Footnote 5 In 2016, in line with the objectives of the Obama administration, Congress instructed that Cyber Command should be made into its own Unified Combatant Command.Footnote 6

On May 4, 2018, nearly a year after Trump's memorandum, Cyber Command was officially elevated to a Unified Combatant Command, becoming the tenth overall combatant command at the time.Footnote 7 Cyber Command describes its mission as aiming “to direct, synchronize, and coordinate cyberspace planning and operations to defend and advance national interests in collaboration with domestic and international partners.”Footnote 8 More specifically:

The Command has three main focus areas: Defending the [Department of Defense (DoD) Information Network], providing support to combatant commanders for execution of their missions around the world, and strengthening our nation's ability to withstand and respond to cyber attack.

The Command unifies the direction of cyberspace operations, strengthens DoD cyberspace capabilities, and integrates and bolsters DoD's cyber expertise. USCYBERCOM improves DoD's capabilities to operate resilient, reliable information and communication networks, counter cyberspace threats, and assure access to cyberspace. USCYBERCOM is designing the cyber force structure, training requirements and certification standards that will enable the Services to build the cyber force required to execute our assigned missions. The command also works closely with interagency and international partners in executing these critical missions.Footnote 9

On September 20, 2018, the Trump administration released a new National Cyber Strategy,Footnote 10 the contents of which indicate an interest in increasing the military's capacity for offensive cyber operations.Footnote 11 The Strategy contains four “pillars.”Footnote 12 Not all of these are directly related to military cybersecurity, but the third pillar—entitled “Preserve Peace through Strength”— provides: “Cyberspace will no longer be treated as a separate category of policy or activity disjointed from other elements of national power. The United States will integrate the employment of cyber options across every element of national power.”Footnote 13 The Strategy lists the following objectives for this pillar: “[i]dentify, counter, disrupt, degrade, and deter behavior in cyberspace that is destabilizing and contrary to national interests, while preserving United States overmatch in and through cyberspace.”Footnote 14 The Department of Defense released a Fact Sheet alongside the Strategy that notes a few more “key themes” of the Strategy, such as “[u]sing cyberspace to amplify military lethality and effectiveness” and “[d]efending forward, confronting threats before they reach U.S. networks.”Footnote 15 In a press conference announcing the Strategy, National Security Advisor John Bolton emphasized that the United States intended to “through both offensive and defensive cyber actions … create structures of deterrence that will reduce malign behavior in cyberspace.”Footnote 16

For its part, Congress signaled some support for a broader emphasis on military cyber operations in the National Defense Authorization Act for Fiscal Year 2019 (NDAA for 2019), which passed in August of 2018. Section 1636 provides that “[i]t shall be the policy of the United States … that the United States should employ all instruments of national power, including the use of offensive cyber capabilities, to deter … and respond to when necessary, all cyber attacks or other malicious cyber activities of foreign powers that target United States interests.”Footnote 17 Section 1642 addresses more potential threats, narrowing in specifically on Russia, China, North Korea, and Iran, and providing:

In the event that the National Command Authority determines that the Russian Federation, People's Republic of China, Democratic People's Republic of Korea, or Islamic Republic of Iran is conducting an active, systematic, and ongoing campaign of attacks against the Government or people of the United States in cyberspace, including attempting to influence American elections and democratic political processes, the National Command Authority may authorize the Secretary of Defense, acting through the Commander of the United States Cyber Command, to take appropriate and proportional action in foreign cyberspace to disrupt, defeat, and deter such attacks under the authority and policy of the Secretary of Defense to conduct cyber operations and information operations as traditional military activities.Footnote 18

In addition to elevating the role of cyber operations within the military, the Trump administration has demonstrated an interest in building up the military's capabilities in space. On March 23, 2018, the White House released a fact sheet providing details on a new National Space Strategy, noting that one aim of the strategy was to “strengthen U.S. and allied options to deter potential adversaries from extending conflict into space and, if deterrence fails, to counter threats used by adversaries for hostile purposes.”Footnote 19

On June 18, 2018, noting that “it is not enough to merely have an American presence in space, [the United States] must have American dominance in space,” Trump “direct[ed] the Department of Defense and Pentagon to immediately begin the process necessary to establish a Space Force as the sixth branch of the armed forces.”Footnote 20 Two months later on August 9, Vice President Pence delivered a speech at the Pentagon regarding national security and space. Justifying the need for a Space Force, he noted that “our adversaries have been working to bring new weapons of war into space itself.”Footnote 21 He specifically referenced actions by Russia and China, including China's 2015 “creat[ion of] a separate military enterprise to oversee and prioritize its warfighting capabilities in space.”Footnote 22

Released the same day as Pence's speech, a report by the Department of Defense made clear that some changes would be undertaken by the executive branch but that “[e]stablishing a sixth branch of the Armed Forces requires Congressional action.”Footnote 23 With respect to steps that could be taken by the executive branch:

First, DoD will establish a Space Development Agency to develop and field space capabilities at speed and scale. The Air Force has already begun to transform its Space and Missile Center (SMC). The Department will accelerate and extend this transformation to all services by creating a joint Space Development Agency.

Second, the Department will develop the Space Operations Force to support the Combatant Commands. These joint space warfighters will provide space expertise to combatant commanders and the Space Development Agency, and surge expertise in time of crisis to ensure that space capabilities are leveraged effectively in conflict.

Third, the Department will create the governance, services, and support functions of the Space Force. Many of these will require changes to U.S. law. The Department will build a legislative proposal for Congressional consideration as a part of the Fiscal Year 2020 budget cycle.

Fourth, the Department will create a U.S. Space Command, led by a four star general or flag officer, to lead the use of space assets in warfighting and accelerate integration of space capabilities into other warfighting forces. U.S. Space Command will be responsible for directing the employment of the Space Force.Footnote 24

With respect to the final action step—the establishment of a U.S. Space Command—it remains unclear whether this will result in an eleventh Unified Combatant Command (in addition to Cyber Command and the nine other existing ones) or will instead be lodged within the existing U.S. Strategic Command. The NDAA for 2019 had instructed the Department of Defense to establish U.S. Space Command as a subordinate unified command within U.S. Strategic Command.Footnote 25 On December 18, 2018, however, Trump issued a memorandum to “direct the establishment, consistent with United States law, of United States Space Command as a functional Unified Combatant Command.”Footnote 26 The executive branch has requested that Congress repeal the just-mentioned language from the NDAA for 2019 so that there will be no impediment to making U.S. Space Command into a Unified Combatant Command.Footnote 27

The Trump administration is also pursuing legislation to make the Space Force the sixth branch of the armed services.Footnote 28 On March 1, 2019, the Department of Defense proposed such legislation to Congress. Rather than creating the Space Force as a wholly independent branch, the proposal places the Space Force within the Air Force, akin to how the Marine Corps sits within the Navy.Footnote 29 Although Trump had originally envisioned the Space Force as an entirely independent military branch,Footnote 30 earlier in the spring he had signaled his openness to this nested placement as an initial step.Footnote 31 Reception to the proposal in Congress has been mixed to date,Footnote 32 and most recently lawmakers have informed Acting Defense Secretary Patrick Shanahan that more budget details are needed for the Space Force, as well as for U.S. Space Command and the Space Development Agency.Footnote 33

The U.S. military restructuring with respect to cyber operations and space does not directly implicate issues of international law. To the extent that this reshuffling results in operational actions, however, it remains to be seen how such actions will fit into the existing international legal framework. International law on the use of force and international humanitarian law are generally applicable. The specifics of how these laws apply to cyber operations have been the subject of considerable interest, with the Tallinn Manual 2.0 often looked to as the most significant piece of work on the subject to date.Footnote 34 With respect to space, the United States is a party to the Outer Space Treaty, which bans certain military actions in space,Footnote 35 and there are other sources of law specifically focused on space that are potentially relevant as well.Footnote 36

In a related development one month earlier, Trump reportedly ordered the reversal of an Obama administration directive, known as Presidential Policy Directive 20 (PPD-20), which placed restrictive interagency approval requirements on any offensive cyber operation.

The Trump administration has since replaced PPD-20 with National Security Presidential Memorandum 13 (NSPM-13), the text of which has not been made public, but which reportedly “frees the military to engage, without a lengthy approval process, in actions that fall below the ‘use of force’ or a level that would cause death, destruction or significant economic impacts.” Ellen Nakashima, White House Authorizes “Offensive Cyber Operations” to Deter Foreign Adversaries, Wash.
