A Sovereign Peace: Reconceptualizing The Law Of Sovereignty In The Taiwan Strait, Alyssa Resar

International Law Studies

China and Taiwan’s enduring dispute stems from a fundamental disagreement over Taiwan’s sovereignty. Drawing on binary conceptions of sovereignty in international law, the Chinese government argues that there can only be one legitimate Chinese sovereign—and that China is this sovereign. Meanwhile, Taiwan’s current government maintains that the Republic of China (Taiwan’s official title) is itself a sovereign, independent entity. As the two governments cling fiercely to their positions, bilateral diplomacy has ceased, and the risk of catastrophic war has risen.

This article argues that international law nonetheless offers the conceptual tools needed to build peace in the Taiwan Strait by …

Iran And Its Proxies: Attribution And State Responsibility, Jennifer Maddocks

International Law Studies

Iran has invested heavily in proxy militias since the regime's founding in 1979. In the decades that followed, groups such as Hezbollah in Lebanon, Shi'a militias in Iraq and Syria, and the Houthis in Yemen have projected Iran's influence across the region. Today, Iran's proxy network is considerably weakened due to Israel's military actions following October 7, 2023, and the fall of the Assad regime in Syria. Yet the Houthis' attacks on Israel and against Red Sea shipping demonstrate how Iran's support to these groups continues to facilitate their conduct in violation of international law. This article examines Iran's potential …

Re-Envisioning Nuclear Deterrence, Raul (Pete) Pedrozo

International Law Studies

This article examines whether the U.S. nuclear umbrella provided to allies is currently viable and whether it is time for the United States to share nuclear weapons technology with its allies in the Asia-Pacific to counter the growing nuclear threat posed by China, North Korea, and Russia. The article discusses the current capabilities and nuclear doctrine of States possessing nuclear weapons, as well as Iran’s nascent nuclear weapons program. It then discusses the current international law and regulatory regime applicable to nuclear weapons. It analyzes the threats posed by China’s and Russia’s nuclear capabilities, and how they affect U.S. nuclear …

Normative Contestation In The International Order: Is China Remaking Global Governance?, Kal Raustiala

International Law Studies

This essay explores China’s approach to global order. China’s remarkable rise has coincided with increasing engagement with the institutions of global governance. These institutions—in particular the United Nations—make up the core of what U.S. leaders have often referred to as the liberal world order or the rules-based order. Many U.S. officials see China as a deep threat intent on challenging, and perhaps even seeking to replace, this rules-based order. This essay, however, makes the case that China’s near-term goals for global governance appear more modest. Much of China’s behavior within institutions such as the UN suggests that what it seeks …

Intervention, Force & Coercion: A Historical Inquiry On The Evolution Of The Prohibition On Intervention, Mohamed S. Helal

International Law Studies

In the Nicaragua Case, the International Court of Justice described coercion as the “very essence of prohibited intervention.” The characterization of coercion as an essential element of non-intervention has become unquestioningly accepted by States and scholars and has dominated debates on how the prohibition on intervention applies in various contexts, including in relation to economic sanctions and cyberoperations. This article challenges the ICJ’s assertion. It does so by retracing the history of the evolution of the prohibition on intervention. It begins by surveying the travaux préparatoires of three Inter-American treaties in which non-intervention was first codified, and then explores the …

Maritime Incidents In The South China Sea: Measures Of Law Enforcement Or Use Of Force?, Aurel Sari

International Law Studies

China has sought to extend its control over the South China Sea at the expense of neighboring countries. In pursuing its goals, Beijing adopts a “power and law” approach, claiming extensive territorial and maritime rights in contravention of the UN Convention on the Law of the Sea and asserting these rights through coercive action in disputed waters. A key element of China’s strategy involves the use of coast guard and maritime militia vessels in an effort to portray its operations as measures of law enforcement, rather than displays of coercive power.

This article argues that the Chinese narrative of law …

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 …

China’S New Law On Foreign Relations: Transforming The Rules-Based International Order With Chinese Characteristics, Raul (Pete) Pedrozo

International Law Studies

In 2023 China adopted a comprehensive Law on Foreign Relations. Although the law is intended to shape China’s diplomatic relations and its cultural, economic, and other exchanges, as well as China’s relations with the United Nations and other international organizations, implementation of the law will be guided by (inter alia) Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era. The law makes clear that China’s foreign relations will be conducted to uphold its system of socialism with Chinese characteristics, safeguard its sovereignty, unification and territorial integrity, and promote its economic and social development. This revisionist “rule by …

Anatomy Of China’S Maritime Strategy: Threatening The Maritime Order Through Its National Legislation And Self-Centered Interpretation Of Unclos, Shigeki Sakamoto

International Law Studies

While the 1982 United Nations Convention on the Law of the Sea (UNCLOS) establishes an objective framework for the coordinated handling of the use of the sea by States in the exercise of their legislative, judicial, and executive powers, China’s legislative bodies, in enacting domestic laws for the fulfillment of treaty obligations, distort obligations in its domestic laws to secure their own national interests. For example, Article 6.2 of China’s Territorial Sea Law violates articles of UNCLOS by denying the right of innocent passage. In addition, China is extending its jurisdiction over security to the contiguous zone with Article 13 …

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 …

Double Classification Of Non-Consensual State Interventions: Magic Protection Or Pandora’S Box?, Pauline Lesaffre

International Law Studies

The classification under international humanitarian law of certain cross-border armed conflicts against an organized armed group remains controversial. More specifically, cross-border armed conflicts resulting from a non-consensual State intervention, such as the United States’ intervention in Syria (without Syrian consent) against the Islamic State, still divide legal scholarship regarding their appropriate classification. One theory argues for a single classification of non-international armed conflict between the intervening State and the organized armed group; another theory relies on a double classification of non-consensual State interventions, adding to the non-international armed conflict an international armed conflict between the intervening State and the territorial …

The Prohibition On Intervention Under International Law And Cyber Operations, Ori Pomson

International Law Studies

Given that cyber technologies have made way for attempts to influence the affairs of other States in novel and unique ways, scholars have turned to the international legal rule which is prima facie most relevant in addressing such meddling; namely, the prohibition on intervention. Moreover, there appears to be quite a wide-ranging consensus in scholarship that the prohibition on intervention applies to a broad range of cyber operations. In contrast to such scholarship, this article argues that, under the lex lata, the prohibition on intervention only applies to acts amounting to a use of force or constituting support for …

The Un Security Council And The Saga Of “Global Legislation”, Gadi Ezra

International Law Studies

The release of the UN Security Council from the “veto chains” that characterized the Cold War has led it to intensively engage in a wide spectrum of conflicts and issues. This expanded activity has peaked around its “global legislation” attempts. Although often used in the legal literature, this term is vague and contested. Scholarly work occasionally discusses the Council’s alleged global legislation, but without initially offering a proper working definition of the term. Arguments both for and against are frequently laid incoherently and can roughly be divided into two types: those assessing the Council’s authority to engage in global legislation, …

Drawing The Cyber Baseline: The Applicability Of Existing International Law To The Governance Of Information And Communication Technologies, Dapo Akande, Antonio Coco, Talita De Souza Dias

International Law Studies

"Cyberspace" is often treated as a new domain of State activity in international legal discourse. This has led to the assumption that for international law to apply to cyber operations carried out by States or non-State actors, "cyber-specific" State practice and opinio juris must be demonstrated. This article challenges that assumption on five different bases. First, it argues that rules of general international law are generally applicable to all domains, areas, or types of State activity. In their interpretation and application to purported new domains, limitations to their scope of application cannot be presumed. Second, this article demonstrates that the …

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 …

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 …

Confronting Space Debris Through The Regime Evolution Approach, Gershon Hasin

International Law Studies

This article examines the complex policy problem of space debris and elaborates a proposal for a bottom-up cooperative regime for its mitigation. While debris proliferation generates costs and threatens the safety of personnel and equipment, this policy problem is compounded by the realization that debris constitutes a by-product of desirable space activities which facilitate national progress and domestic increases in values. It is further complicated by increased private participation, conflicting interests of participants, and a global order susceptible to outlier behavior.

Scholars attempting to tackle this policy problem have failed to appreciate the complex legislative process through which international rules …

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 …

Is A South China Sea Code Of Conduct Viable?, Raul (Pete) Pedrozo

International Law Studies

For over twenty years, the People’s Republic of China (PRC) has stonewalled efforts by the Association of Southeast Asian Nations (ASEAN) to negotiate a binding Code of Conduct that would form the basis for a peaceful and durable solution to the territorial and maritime disputes in the South China Sea (SCS). At the same time, the PRC engaged in a series of malign activities, to include the militarization of several reclaimed artificial islands, that have forever changed the landscape and status quo of the SCS. In 2020, the PRC unexpectedly called on ASEAN to resume the negotiations as soon as …

Enclosure Of The Oceans Versus The Common Heritage Of Mankind: The Inherent Tension Between The Continental Shelf Beyond 200 Nautical Miles And The Area, Michael W. Lodge

International Law Studies

The 1982 United Nations Convention on the Law of the Sea (UNCLOS) is a major achievement of diplomacy in the late twentieth century and is rightly regarded as the “constitution for the ocean.” UNCLOS has withstood the test of time and has demonstrated its flexibility and adaptability to changing circumstances. Notwithstanding, there is an underlying tension at the heart of UNCLOS as it tries to reconcile two fundamentally different approaches—the exclusivity of coastal State jurisdiction versus the international character and shared space of the Area beyond national jurisdiction. As the search for mineral deposits in the Area intensifies, and as …

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, …

Foreign Cyber Interference In Elections, Michael N. Schmitt

International Law Studies

In the 2020 U.S. elections, Russia authorized and conducted influence operations designed to support former President Trump, although it did not attempt to alter any technical aspect of the voting process. Russia was not alone. Iran mounted a multi-pronged covert influence campaign intended to undercut Trump’s reelection prospects, while other foreign actors–like Lebanese Hizballah, Cuba, and Venezuela–also tried to influence the election. Interestingly, China did not conduct operations designed to alter the outcome, although it did consider doing so. The phenomenon of election meddling, however, extends well beyond the United States to such countries as Austria, Estonia, France, Germany, Hungary, …

Military Action To Recover Occupied Land: Lawful Self-Defense Or Prohibited Use Of Force? The 2020 Nagorno-Karabakh Conflict Revisited, Tom Ruys, Felipe Rodriguez Silvestre

International Law Studies

In September 2020, heavy fighting erupted between Armenia and Azerbaijan in and around Nagorno-Karabakh, a region of Azerbaijan long controlled by Armenia. After two months of military confrontations, a tripartite ceasefire was concluded, drastically altering the pre-existing territorial status quo.

The "Second Nagorno-Karabakh War" brings to light a fundamental question for international law on the use of force—and one that has received limited attention in legal doctrine. The question is this: when part of a State’s territory is occupied by another State for an extended period of time, can the former still invoke the right of self-defense to justify …

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 …
