Narrowing “The Gap”: Counter Gray Zone Operations, Raul (Pete) Pedrozo

International Law Studies

China is exploiting "The Gap" by conducting provocative Gray Zone operations to challenge its neighbors' sovereignty and sovereign rights, as well as their navigational rights and freedoms, in waters off their coast in the East China Sea, Taiwan Strait, and South China Sea. By engaging in malign activities that fall below the threshold of an "armed attack," China anticipates it can incrementally advance its interests without eliciting a military response from the targeted States. Diplomatic protests and third-party dispute settlement have not convinced China to halt its aggressive behavior. This article suggests States should use non-lethal counter-piracy tactics, techniques, and …

Collective Attribution In Cyberspace: A Rebranded Version Of Attribution Does Not Make It More Effective, Dan Efrony

International Law Studies

The international community has been unsuccessful in establishing an effective legal framework for holding States accountable for cyber wrongdoing. Instead, official political attribution—collectively denouncing States for irresponsible conduct in cyberspace—has become a common substitute to encourage compliance with voluntary non-binding international norms. Since December 2017, the United States and United Kingdom, along with their closest allies, have embraced and implemented collective attributions and responses. They thereby seek to shape “rules of the road” for responsible State behavior in cyberspace and to enhance accountability and deterrence. However, these attributions rely primarily on the outcomes of American and British attribution processes that …

Protecting The Free Flow Of Commerce From Houthi Attacks Off The Arabian Peninsula, Raul (Pete) Pedrozo

International Law Studies

This article reviews recent maritime incidents involving Houthi missile and drone attacks on commercial shipping and foreign warships off the Arabian Peninsula, purportedly in response to the Israeli military operations in Gaza following the October 7, 2023, Hamas-led attack that killed over 1,300 Israeli civilians. The article discusses the legality of the U.S. response to those incidents, including U.S. counter-piracy operations and the right of unit and collective self-defense. The article also discusses whether the United States should consider conducting land-based attacks on Houthi missile and drone sites in Yemen under the principle of self-help to preempt further attacks on …

One Treaty To Apply Them All? Defining Maritime Terrorism By Cross-References And Reservations: The Asean Region Example, Arron N. Honniball

International Law Studies

Defining terms will shape a State’s treaty obligations, the domestic legislation necessary, the availability of cooperative mechanisms, and norm diffusion. Maritime terrorism is an umbrella term referring to the piecemeal approach of treaties creating offenses for identified acts at sea. Further treaties cross-reference the offenses in a selection of global instruments to create related offenses. This includes financing of terrorism (Convention for the Suppression of the Financing of Terrorism (ICSFT)) and regional maritime terrorism (ASEAN Convention on Counter Terrorism (ACCT)). All cross-referenced instruments shall apply to define ICFST or ACCT offenses unless a State excludes, by reservation, a cross-referenced instrument …

Assessing The Legal Framework For Potential U.S. Conflict With China Over Taiwan, Shawn W. Brennan

International Law Studies

The People’s Republic of China has clearly stated the importance of resolving the Taiwan question and realizing China’s complete “reunification” to end their century of humiliation. As China grows as the most significant strategic competitor to the United States and develops the military capability to force the issue, understanding what legal authorities the President may exercise in ordering a response is increasingly urgent. This article reviews the legal authorities for the use of force by the United States and examines the contours of the President’s authorities and where they intersect with Congress’s authorities. Through various hypothetical scenarios involving attempts by …

Intelligence Collection And The International Law Of The Sea, James Kraska

International Law Studies

This article explores the legal implications of intelligence collection operations at sea. It concludes that in terms of the international law of the sea, intelligence collection that occurs outside of the territorial sea is lawful. Furthermore, even intelligence collection by a foreign ship inside the territorial sea, while a violation of State sovereignty, may not violate the law of the sea, per se. Additionally, within the territorial sea, coastal States are limited in the measures they may take against foreign-flagged submarines and surface warships collecting intelligence since those activities do not constitute an armed attack or even the use of …

Australia’S Maritime Security Challenges: Juggling International Law And Informal Agreements In An International Rules-Based Order, Natalie Klein

International Law Studies

Australia has voiced its commitment to the “rules-based order” since 2008 and the rules-based order has become a touchpoint of both Australian defense and foreign policy. Australia has also voiced its commitment to international law, particularly the UN Convention on the Law of the Sea, to meet challenges to the maritime rules-based order, including in the South and East China Seas. References to international law have often been bundled in or left adjacent to the rules-based order and the two terms are not synonymous. This article discusses the role of international law in the rules-based order as it relates to …

In Defense Of Pure Sovereignty In Cyberspace, Kevin Jon Heller

International Law Studies

States currently endorse three different positions concerning the international wrongfulness of cyber operations that penetrate computer systems located on the territory of another state but do not rise to the level of a use of force or prohibited intervention. The first position is that such low-intensity cyber operations are never wrongful, because sovereignty is a principle of international law, not a primary rule that can be independently violated. The second is that low-intensity cyber operations are always wrongful, because sovereignty is a primary rule of international law that is violated by any non-consensual penetration of a computer system located on …

Intelligence Sharing In Multinational Military Operations And Complicity Under International Law, Marko Milanovic

International Law Studies

This article examines the international legal framework applicable to intelligence sharing in multinational military operations, with a particular focus on complicity scenarios. It first provides a theoretical overview of the role of fault in complicity, of how intent and knowledge can be conceptualized, and of the attribution of fault to States. It then looks in detail at the rule codified in Article 16 of the International Law Commission’s Articles on State Responsibility, and argues that this rule is best understood as employing multiple modes of fault (direct and indirect intent and wilful blindness). The article also argues that international humanitarian …

The Plea Of Necessity: An Oft Overlooked Response Option To Hostile Cyber Operations, Louise Arimatsu, Michael N. Schmitt

International Law Studies

States are increasingly focused on the measures—cyber or otherwise—that they can take in response to hostile cyber operations. Although cyber operations are usually responded to with acts of “retorsion” (acts that are lawful, although unfriendly), international law recognizes other self-help mechanisms that allow for more robust responses. In the cyber context, most attention has focused on countermeasures and self-defense. Yet, both are subject to various limitations that constrain their availability.

This article examines a further option, the so-called “plea of necessity.” It allows States to respond to a hostile cyber operation when the action taken would otherwise be unlawful but …

Cyber Attribution And State Responsibility, William Banks

International Law Studies

We might expect international law to specifically address cyber attribution requirements due to the significance of attribution in framing the legal responsibility of States and the boundaries of responsive actions by victim States. However, there is little international law of cyber attribution, and what law there is exists largely by implication. Likewise, there is only a murky and highly contested law of State responsibility that theoretically constrains the vast majority of State-sponsored cyberattacks. Because victim States cannot engage in countermeasures unless they attribute a cyberattack to a State, attribution can serve simultaneously to constrain and empower victim States. However, the …

Application Of The Due Diligence Principle To Cyber Operations, Tomohiro Mikanagi

International Law Studies

The discreet use of proxies by States renders it difficult to prove attribution to States under the existing rules of attribution. On the other hand, the due diligence principle, if applicable, does not require attribution but can lead to the invocation of State responsibility for cyber operations emanating from the territory of other States. In the Corfu Channel judgment the ICJ recognized “every State’s obligation not to allow knowingly its territory to be used for acts contrary to the rights of other States,” and UN Member States agreed that existing international law applies to cyber operations. However, the UN Members …

Neutrality And Cyberspace: Bridging The Gap Between Theory And Reality, Noam Neuman

International Law Studies

While there exists a broad consensus among States that international law generally applies to the cyber domain, particular views regarding the applicability of the law of neutrality have rarely been put forward, and presently there seems to be insufficient State practice and domain-specific opinio juris in this regard. Against this backdrop, several attempts have been made throughout the years to apply certain neutrality rules to cyberspace by referring to analogies from other domains. However, this legal regime provides an emblematic example of what the introduction of traditional rules of international law, formulated with the physical domains of warfare in mind, …

U.S. Recognition Of Japanese Sovereignty Over The Senkaku Islands, Raul (Pete) Pedrozo

International Law Studies

Every U.S. administration from Truman to Kennedy recognized Japanese residual sovereignty over the Senkaku Islands. U.S. policy changed, however, to one of neutrality under the Nixon administration during the negotiations of the Okinawa Reversion Treaty. The change in policy was not based on a belief that Japan did not retain sovereignty over the islands, but rather was done to appease the Republic of China over its impending expulsion from the United Nations and to break an impasse of the ongoing textile negotiations with Taipei. The administration’s overtures to China, culminating in Nixon’s visit to China contributed to the decision. Since …

Legal Reviews Of War Algorithms, Tobias Vestner, Altea Rossi

International Law Studies

States and scholars recognize legal reviews of weapons, means or methods of warfare as an essential tool to ensure the legality of military applications of artificial intelligence (AI). Yet, are existing practices fit for this task? This article identifies necessary adaptations to current practices. For AI-enabled systems that are used in relation to targeting, legal reviews need to assess the systems’ compliance with additional rules of international law, in particular targeting law under international humanitarian law (IHL). This article discusses the procedural ramifications thereof. The article further finds that AI systems’ predictability problem needs to be addressed by the technical …

Maritime Police Law Of The People’S Republic Of China, Raul (Pete) Pedrozo

International Law Studies

China’s new Maritime Police Law (MPL) purports to regulate the duties of China’s maritime police agencies, including the China Coast Guard, and safeguard China’s sovereignty, security, and rights and interest. The MPL has potentially far-reaching application, as China claims extensive maritime areas off its mainland and in the South China Sea. This expansive application of maritime law enforcement jurisdiction is problematic given that most of China’s maritime claims are inconsistent with international law. To the extent that the MPL purports to assert jurisdiction over foreign flagged vessels in disputed areas or on the high seas, it contravenes international law. Numerous …
