  • Borders as Systems of Continuity and Discontinuity in the Age of Trump
  • Margath A. Walker

How can we understand the implications of the Trump administration's promise to expand the border wall between the US and Mexico for Latin American Geography? This question demands recounting the constitutive elements of critical and progressive scholarship. To paraphrase Noam Chomsky: Our role as scholars and teachers is to find out and tell the truth as best we can about things that matter and communicate that truth to the right audience (Chomsky 1996).

At a surface level, that task requires replacing misinformation in a 'fact-free' universe with reliable data. More deeply, it means attention to the continuity and discontinuity of borders. Border scholarship continues to be theoretically sophisticated and empirically rich (for an overview of this literature see Sidaway 2015; Walker and Winton 2017). I advocate here for a systemic approach which highlights the similarities replicated through security-based strategies (i.e., continuity), along with the multi-scalar cacophonous contradictions of fortification (i.e., discontinuity). Walls are not simply about blockage. They are also about movement and spatial relationships. It is crucial to document that complexity in the current political climate. Incorporating the lessons from robust debates within and beyond Latin American geography (e.g., Monsiváis 1981; Berger 1995; Blomley 2008; Escobar 2010; Gaffney et al. 2016; Mollett 2017) ensures: 1) attention to the unequal power [End Page 173] structures throughout the region (Finn and Hanson 2017); 2) awareness of the geographical and discursive mechanisms at work in the construction and maintenance of regions; and 3) continued motivation to interrogate who wins and who loses. My experience on Mexico's northern and southern borders serves as a poignant reminder of these three points and informs my argument here.

By now we are familiar with the threat of a "big beautiful wall" through the Executive Order "Border Security and Immigration Enforcement Improvements" as well as the Department of Homeland Security's litany of ambitions. Proposed plans include publicizing crimes by undocumented immigrants, enlisting local law enforcement as immigration enforcers, the construction of new detention facilities, and increased deportations. Quite obviously, fortifying political boundaries is nothing new. However, border walls are experiencing a renaissance (Jones and Johnson 2016). This, in spite of evidence that such constructions are ineffective and, in the US at least, a paradoxical response to the fact that more Mexicans voluntarily departed the US for Mexico than entered the country from 2009 to 2014 (Miller 2014b).

At the national scale, we see little acknowledgement of borders as interrelated systems. The wall is a perfect example. The border exists at the edge of US territory as an entity that conditions flow and movement. But of course it doesn't work that way. Mexico is imbricated in a complex dynamic of geopolitical hierarchies operating at multiple scales. On the northern border US policy mechanisms dominate, and on the southern border with Guatemala and Belize, an historically porous area is becoming increasingly fortified and controlled. In 2014, Mexican President Enrique Peña Nieto under pressure from the United States to manage the flows of Central American youth traveling to the US-Mexico border, launched the Southern Border Plan (Programa Frontera Sur (Miller 2014a). That plan can be read as a useful corollary to current fortification practices in the US. Politically, Mexico's borders have become strongly interconnected. To draw on work by Mexican writers and scholars, Mexico is itself a wall that acts as a buffer between the US and Central America's "Northern Triangle" (Porter 2017; Castañeda 2017). To put it crudely, Mexico has been doing the dirty work for us. Whether or not the US-Mexico wall materializes as Trump envisions it, the message has trans-scalar systemic reverberations.

The deteriorating bilateral relationship has received significant coverage in the press. In a recent interview, Mexican Senator Armando Ríos Piter characterized the wall as a hostile, unfriendly act. The senator cautioned against alienating Mexico as a partner, and highlighted the security work Mexico has performed on behalf of its northern neighbor (Here and Now 2017). Last year, Mexico sent back nearly twice as many Central Americans as the United States (Semple...
