On a December morning in 2015, H.A. left early from his home in central Gaza to tend to his fields of wheat, barley, peas, and fava beans a couple hundred meters from the Israeli border fence. He arrived to find a low-flying Israeli aircraft spewing a thick, white substance over his farmland as it traveled south along the Palestinian side of the divide. Two days later, H.A. observed signs of damage to the leaves of his plants. Within ten days, his entire crop had shriveled and died, leaving him without his only source of income and unable to repay a loan for agricultural inputs.1
Like many Palestinians, a substantial portion of H.A.’s lands lies within the Israeli-imposed “no-go zone” inside the Gaza Strip, which in recent years has also been converted into a “no-grow zone” for farmers.2 Facing threats of rocket attacks, improvised explosive devices (IEDs), and border infiltration, Israel sprays herbicides throughout this area in order to preserve a clear line of sight.3 Access to certain areas is restricted entirely, with Israel regularly firing on encroaching Palestinians, civilians and militants alike.4 The Israel Defense Forces (IDF) have issued contradictory pronouncements as to the precise boundaries and rules of the no-go zone,5 but Gazan farmers have found it wisest to abandon most lands within one hundred meters of the border.6 Those who approach an even more intermediate range do so at great peril—dozens of Palestinian civilians have been killed and hundreds injured by IDF munitions in this murky region since Israel withdrew from Gaza in 2005.7
Gaza’s no-go zone is an instance of a familiar tool in international politics: the buffer zone. Long favored as a means of defusing conflict, buffer zones have been employed on nearly every continent over the course of history. An early European application was the “neutral ground” that separated Spanish and British encampments in Gibraltar in the eighteenth century.8 Other notable, bygone examples include those established by the Concert of Europe (in the Netherlands, Scandinavia, and Switzerland),9 the Treaty of Versailles (German Rhineland),10 the Tanggu Truce (Chinese Manchuria),11 and the Geneva Conference (North and South Vietnam).12 Buffer zones were inaugurated as conditions of the independence of Norway from Sweden13 and of several Baltic states from Russia.14
In modern times, similar and long-standing arrangements can be found in regions as diverse as Cyprus, Korea, and Sinai.15 On one hand, the appeal of creating distance between hostile states—either by mutual agreement, unilateral withdrawal, or forcible population removal—is obvious: if, as realists theorize, states are conceived as opaque “billiard balls” colliding with one another in an anarchic world order,16 then buffer zones provide a layer of cushioning between them. Yet while realists tend to focus on state actors,17 buffer zones also provide capacity for dealing with nonstate actors, allowing governments to “pursue rebels or terrorists”18 beyond their territorial borders or, alternatively, to patronize fifth columns19 in enemy states.
In either sense, the establishment of a buffer zone necessarily entails a sacrifice of sovereignty, whether willful or not, and often bears disastrous consequences for civilians like H.A. caught within. From an international-law standpoint, H.A. could theoretically pursue a variety of legal avenues in a claim against Israel, invoking the UN Charter’s guarantee of state sovereignty (bracketing momentarily the issue of Palestinian statehood), the Geneva Conventions’ safeguard of civilians in armed conflicts, and international customary law’s protection of private property rights.
But the enigmatic nature of buffer zones leaves the applicability of these sources of law—and thus the legal remedies available to impacted civilians—very much in doubt. Neither zones of war nor peace, neither fully sovereign nor militarily occupied, buffer zones seem to fall through the cracks of international law, “function[ing] in a legal grey area whereby jus ad bellum or jus in bello norms are temporarily suspended.”20 As a result, little legal action has been taken with respect to the rights of civilians within buffer zones.21
This ambiguity persists primarily because the law of buffer zones has yet to receive focused legal attention as a field of its own, both from a “jus ad buffer zone” and a “jus in buffer zone”22 perspective. This Comment fills that gap by providing a conceptual framework to classify different modes of buffer zones and to assess their legal consequences. Part I presents a novel definition of international buffer zones, emphasizing the loss-of-sovereignty aspect. With this concept in mind, Part II develops the conditions under which introducing a buffer zone might be sanctioned under international law. Part III then addresses the governing law within buffer zones, focusing on restrictions of civil rights, the destruction of property, and the rules of military engagement. Finally, Part IV considers whether civilians adversely affected by the operation of a buffer zone could pursue a legal remedy against the state responsible under an international-law takings theory. This Comment utilizes case studies throughout its exploration to illustrate real-world applications of legal principles.
