In my previous articles, Frontier Deterrence: A Real Security Challenge. Part I: The Keys to a Necessary Border Security Agenda in the United States, published in December 2024, and Frontier Deterrence: A Real Security Challenge. Part II: Prevention and Containment in Redefining Border Management Facing Transversal Threats, published in January 2024, I laid the foundation for the PCCR model (Prevention, Containment, Concretion, and Reaction). These articles explored how the initial phases of the model can strengthen state sovereignty, mitigate security threats, and foster regional stability in the face of challenges such as irregular migration and transnational criminal networks.

The initial analysis highlighted transversal threats, which transcend national borders and economic sectors, simultaneously impacting security, social cohesion, and economic stability. These threats, when poorly managed, erode perceptions of state sovereignty and generate political, social, and economic tensions. Irregular migration, in particular, becomes a critical challenge by overwhelming administrative and border systems, facilitating illicit activities such as drug trafficking, human trafficking, and institutional corruption.

The phases of Prevention and Containment, detailed in previous articles, focus on anticipating and mitigating risks from their earliest stages. Prevention involves understanding and addressing the root causes of migration, such as poverty, violence, and political instability, while Containment emphasizes limiting the impact of emerging crises through rapid and effective responses. These phases establish the groundwork for strategic border management by combining rigorous planning, risk assessments, and targeted responses.

In this third article, I complete the framework of the PCCR model by examining the phases of Concretion and Reaction, which translate strategic policies into operational actions and immediate responses to crises. This final analysis demonstrates how these components transform border management into a dynamic process that addresses current needs while preparing for future challenges in a sustainable and adaptive manner.

Understanding the PCCR Formula: a comprehensive model for strategic construction

The PCCR formula is more than just a sequence of phases; it represents a comprehensive framework for addressing the multidimensional challenges posed by transversal threats. By integrating prevention, containment, concretion, and reaction into a cohesive strategy, the model enables states to anticipate, mitigate, and respond to complex security issues in a systematic and sustainable manner. Each phase builds upon the previous one, creating a dynamic cycle that adapts to evolving contexts and ensures the alignment of strategic goals with operational realities.

The PCCR formula (Prevention, Containment, Concretion, and Reaction) is designed to provide an integrated response to transversal threats. While the earlier phases address root causes and establish defensive mechanisms, concretion and reaction translate strategic intent into tangible actions and immediate responses.

Concretion: from policy to action

As explained, Concretion is the third phase of the PCCR model, where strategies previously developed during the prevention and containment stages are translated into concrete, measurable, and sustainable actions. This phase is critical to ensuring that migration and security policies do not remain as theoretical plans but are instead materialized into tangible solutions that address immediate needs while strengthening institutional capacity in the long term. Concretion requires not only financial and human resources but also political will and interagency coordination to transform strategic decisions into effective results.

From design to implementation

The transition from strategic policy to operational action demands careful planning that considers available resources, logistical constraints, and short-, medium-, and long-term objectives. In the context of migration management, this transition involves tasks ranging from building border infrastructure to establishing community programs that facilitate migrant integration into host communities.

One of the greatest challenges of concretion is ensuring that policies are applicable and adaptable to diverse contexts. For instance, the needs of a border community in Texas may differ significantly from those of an urban community in New York receiving a large number of migrants. In this sense, concretion requires a decentralized approach that allows local authorities to adapt national policies to their specific realities while maintaining strategic coherence at the national level.

Effective policy implementation must also be supported by monitoring and evaluation systems that measure impact and adjust strategies based on results. This evidence-based approach not only enhances the efficiency of actions but also strengthens public trust in responsible institutions.

Institutional strengthening and modernization

Concretion relies on building robust institutional capacities that can transform policy into action. This requires modernizing administrative infrastructure and enhancing interagency collaboration through technological tools. Biometric identification systems and integrated databases streamline migration tracking, while digital platforms reduce delays in asylum and visa processes. Such advancements ensure resources are used effectively, reinforcing trust in government systems.

Beyond national agencies, partnerships with international organizations, such as the IOM and UNHCR, play a pivotal role. These collaborations provide technical and financial support, expanding the scope of implementation and ensuring that migration flows are managed with both efficiency and humanity.

Building multilateral alliances

In the context of transversal threats, concretion cannot be limited to unilateral actions. Building multilateral alliances is essential to addressing the structural causes of irregular migration and ensuring a coordinated regional response. These alliances should include bilateral agreements between neighboring countries as well as regional initiatives involving multiple actors.

For example, strengthening cooperation between the United States and the Northern Triangle countries of Central America (Honduras, El Salvador, and Guatemala) is key to reducing migration pressure at the southern border. This can be achieved through joint economic development programs, anti-corruption initiatives, and institutional strengthening strategies in the countries of origin. These actions not only address the root causes of migration but also help stabilize affected regions, creating a safer and more prosperous environment for their populations. Similarly, the participation of regional organizations, such as the Organization of American States (OAS), can facilitate policy coordination and resource mobilization at a continental level. These multilateral initiatives must be backed by solid financial commitments and accountability mechanisms to ensure their sustainability and effectiveness.

Addressing the asylum challenge

It is essential to address a critical issue within the U.S. immigration system: the asylum process. Current statistics reveal that only about 15% of asylum applications are approved, with a significant number of these being frivolous claims submitted solely to secure temporary relief in the United States. This misuse of the asylum system has led to an overwhelming backlog of nearly three million cases in immigration courts and more than one million additional cases pending before the U.S. Citizenship and Immigration Services (USCIS).

This scenario underscores a major challenge: the asylum system, originally designed as a lifeline for individuals fleeing persecution, has become an incentive for irregular migration. Migrants seeking to cross the border often view asylum as a strategic tool to delay deportation and secure temporary residency, regardless of whether they meet the stringent criteria required by law. Such abuse not only undermines the credibility of the asylum process but also diverts resources from genuine asylum seekers in dire need of protection.

To address this issue, the asylum process requires comprehensive reform as part of the broader migration strategy outlined in the PCCR model. Strengthening initial screening mechanisms to identify and dismiss frivolous claims early in the process is critical. Enhanced capacity at border entry points, coupled with advanced technology and trained officers, can ensure that genuine claims are prioritized. At the same time, expediting case processing through additional resources, including hiring more immigration judges and officers, will alleviate the backlog and deter individuals who aim to exploit delays in the system.

Disincentives for submitting unfounded claims are equally necessary, such as imposing penalties for false applications while ensuring fairness and preserving the rights of legitimate asylum seekers. Regional cooperation could also play a pivotal role in addressing these challenges. Establishing safe havens in partner countries, supported with financial and logistical aid, would provide alternatives to the U.S. asylum system, thereby reducing the overwhelming influx at its borders.

Public awareness campaigns, targeting both domestic audiences and communities in migrants’ countries of origin, can also help clarify the rigorous criteria for asylum eligibility. By addressing misconceptions about the process and its intended purpose, such efforts could reduce the appeal of asylum as a perceived shortcut to entering the United States.

Balancing security and compassion is vital for any reform. While the asylum process must be protected from abuse, it remains a moral and legal obligation to provide refuge to those genuinely fleeing persecution. A system that ensures efficiency in deterring misuse while upholding the rights of vulnerable individuals reinforces the credibility and integrity of the United States’ humanitarian commitments. By addressing these systemic issues, the U.S. can mitigate a significant incentive for irregular migration, contributing to a more organized and secure border management strategy.

Community integration programs

A crucial aspect of concretion is the implementation of programs that facilitate the integration of migrants into host communities. These programs are essential not only for ensuring the well-being of migrants but also for reducing social tensions and promoting community cohesion.

Integration must be approached from multiple dimensions, including access to education, employment, housing, and healthcare services. For instance, educational programs can include English as a Second Language (ESL) classes, technical training, and cultural orientation to help migrants adapt to their new environment. Similarly, employment initiatives can connect migrants with job opportunities that match their skills and experience while protecting local workers from potential displacement.

Additionally, awareness campaigns directed at host communities are vital for combating misinformation and fostering a positive attitude toward migrants. These campaigns should emphasize the economic and cultural contributions of migrants, highlighting their role as valuable members of society.

Continuous evaluation and adjustment

Concretion is not a static process. To ensure long-term success, it is essential to establish monitoring and evaluation mechanisms that measure the impact of implemented policies and make adjustments based on the results obtained. This includes collecting data on key indicators, such as access to services, employment rates, and community perceptions of migration.

The evidence-based approach also allows for identifying areas of improvement and prioritizing resources more efficiently. For example, if data indicates an increase in social tensions in a specific community, additional resources can be allocated to strengthen integration programs in that area. Similarly, if a job training program proves particularly effective, its reach can be expanded to other regions.

Concretion: The bridge between strategy and action

Concretion is the bridge between strategy and action, where policies designed during the prevention and containment stages materialize into tangible results. This phase requires not only resources and coordination but also a clear vision and constant commitment to ensuring that implemented actions are sustainable and effective. In a context of migration challenges and transversal threats, concretion is an indispensable tool for transforming policies into real solutions that benefit both migrants and host communities, while simultaneously strengthening institutional capacity and regional stability.

Reaction: immediate response to imminent crises

Reaction, as a critical phase of the PCCR model, is responsible for addressing crises that pose direct and immediate threats to national and regional security. Within the context of irregular migration, it is essential to clearly affirm that this phenomenon is not merely a humanitarian or administrative challenge but also a security issue. Recognizing this reality is fundamental for designing and implementing strategic guidelines that, far from being excessive or disproportionate, align with the needs of sovereign protection, social stability, and public order.

The security dimensions of migration pressure

When migration flows exceed institutional capacity, they create systemic vulnerabilities that compromise both community stability and governance effectiveness. These challenges, exacerbated by the infiltration of transnational criminal networks and the exploitation of migrants for labor or trafficking, highlight the broader security implications of unmanaged migration. Addressing this issue requires distinguishing between the structural dynamics of irregular migration and the humanitarian needs of individuals, ensuring that responses are both strategic and compassionate.

The presence of malicious actors exploiting ineffective controls to operate within migration flows is a documented reality. Criminal networks, such as the Tren de Aragua, exploit large-scale migration flows to expand their operations across borders, engaging in illicit activities that destabilize communities. Their presence fosters insecurity, disrupts social cohesion, and erodes public confidence in state institutions. Tackling these networks requires a comprehensive strategy that combines enhanced border controls with collaborative international efforts to dismantle their infrastructure.

Additionally, irregular migration affects security from a structural perspective. The massive arrival of people into regions with limited resources can generate social tensions, inter-community conflicts, and the collapse of critical infrastructure. These dynamics, though not always intentional, create environments conducive to radicalization, the strengthening of xenophobic narratives, and political polarization—all of which exacerbate social instability.

Thus, strategic guidelines that recognize irregular migration as a security problem are neither overreactions nor disproportionate responses. Instead, they represent pragmatic necessities in addressing the complexities of this phenomenon. Ignoring this dimension would be a dangerous omission for states and the communities directly impacted by these effects.

Reaction as a tool to restore control

When migration flows reach levels that threaten national stability and security, reaction becomes an indispensable tool for restoring control. Reactive measures, such as mass deportations, aim not only to resolve an immediate crisis but also to send a clear deterrent message to those planning to enter the country irregularly. While these actions are costly and controversial, their effectiveness lies in their ability to reclaim state sovereignty over territory and borders.

In this context, deporting irregular migrants with criminal records or those who pose clear security risks is not only a legitimate action but also an obligation of the state toward its citizens and governance system. Estimates show that deporting approximately 1.5 million irregular migrants in the United States would cost around $90 billion. Although significant, this investment should be understood as a corrective measure that, alongside preventive and containment strategies, helps reduce the costs of future crises.

However, deportations should not be viewed as a standalone solution. Their implementation must be strategic, respecting human rights and ensuring rigorous adherence to legal processes. This not only reinforces the legitimacy of state actions but also protects the country from international criticism and diplomatic tensions with countries of origin.

Coordinated response against criminal networks

Reacting to transnational criminal networks is another key aspect of this phase. These organizations, which operate beyond borders, are responsible for the majority of abuses and crimes associated with irregular migration flows. Disrupting these networks requires a combination of joint police operations, international cooperation, and the use of advanced intelligence.

An illustrative example is the Tren de Aragua, a criminal organization that has expanded its illicit activities throughout Latin America and into the United States. Tackling this threat demands not only national actions but also coordinated efforts with countries where this network is active, such as Colombia, Brazil, and Chile. Collaboration between security agencies to capture key leaders, confiscate financial resources, and dismantle logistical infrastructures is essential to neutralize their impact.

Furthermore, reacting against these networks should include specific actions to protect affected communities. This may involve creating rehabilitation programs for victims of human trafficking, awareness campaigns to prevent labor exploitation, and implementing witness and collaborator protection policies to help dismantle these organizations.

Deterrence and restoring public confidence

Reaction not only seeks to address immediate crises but also to establish a precedent that reinforces deterrence and public confidence in the state's ability to protect its citizens. Acting firmly against uncontrolled migration flows and criminal networks sends a clear message that security and stability are non-negotiable priorities. This deterrent effect is particularly important in contexts where the perception of state weakness has encouraged irregular migration flows. Reactive actions must be accompanied by a communication strategy that informs the public about the measures adopted, their objectives, and their outcomes. This not only strengthens the state’s legitimacy but also helps counter the narratives of criminal networks that benefit from misinformation.

A balanced and ethical reaction

It is crucial that reaction combines firmness with humanitarian sensitivity. Although security is a priority, reactive policies must not overlook the needs of the most vulnerable groups within migration flows, such as unaccompanied minors, pregnant women, and legitimate asylum seekers. In these cases, reaction must include measures that ensure dignified treatment, access to due process, and the provision of essential services. Establishing temporary processing centers in critical areas can be an effective solution to handle these situations ethically and efficiently. These centers allow for the rapid identification of individuals who pose security threats while providing humanitarian assistance to those in genuine need. Collaboration with international and non-governmental organizations can enhance state capacity to implement these measures without compromising security objectives.

Strategic and ethical implementation

Understanding the dynamics of reaction, irregular migration, when it exceeds state capacity to manage, becomes a security problem that must be addressed with determination and pragmatism. Strategic guidelines that acknowledge this reality are not outbursts but logical and necessary responses to dynamics that threaten sovereignty, stability, and social cohesion. Reaction, as a phase of the PCCR model, is the tool that restores control in critical situations, striking a balance between firmness in protecting security and sensitivity to humanitarian needs. This approach, implemented strategically and ethically, not only resolves immediate crises but also strengthens the state's capacity to face future challenges with confidence and legitimacy.

A comprehensive perspective on frontier deterrence

Frontier Deterrence integrates the PCCR model into a unified strategy that balances security, stability, and social cohesion. This holistic approach recognizes that irregular migration is not merely a border management issue but a multidimensional challenge that intertwines economic, political, and security dimensions. By addressing these interconnected factors, Frontier Deterrence establishes a framework for sustainable and adaptive border management.

The PCCR model—through its phases of prevention, containment, concretion, and reaction—ensures that States are equipped to anticipate, mitigate, and respond to both immediate crises and long-term systemic challenges. For example, prevention targets the root causes of migration, such as poverty and instability, while containment mitigates the impact of sudden migration flows. Concretion translates strategic goals into actionable programs, and reaction provides the mechanisms to address acute crises effectively. Together, these phases form a dynamic cycle that evolves with changing contexts.

Key to the success of Frontier Deterrence is the integration of advanced technologies, multilateral cooperation, and community-focused initiatives. Technological advancements, such as biometric tracking and predictive analytics, enhance operational efficiency and decision-making. Regional alliances and partnerships with international organizations ensure a coordinated and resource-efficient response to shared challenges. Meanwhile, programs that promote the integration of migrants into host communities foster social cohesion, reducing tensions and strengthening societal resilience.

By embedding these elements into its framework, Frontier Deterrence not only resolves current crises but also positions states to confront future threats with resilience, flexibility, and innovation. This comprehensive perspective reflects a commitment to safeguarding sovereignty while upholding humanitarian principles and regional stability.

Final thoughts

As transversal threats grow more complex and interconnected, Frontier Deterrence emerges as an innovative framework that redefines how states approach border security and migration management. By integrating the PCCR model—Prevention, Containment, Concretion, and Reaction—this approach ensures that policies are not only effective but also ethical and sustainable, addressing the multifaceted challenges of modern border management.

The strength of Frontier Deterrence lies in its recognition that border security extends beyond territorial control to encompass economic, social, and political dimensions. It advocates for strategies that balance sovereignty with humanitarian obligations, ensuring that security measures protect communities without compromising individual rights. Through multilateral alliances, technological innovation, and community-focused initiatives, this framework provides the tools necessary to anticipate and mitigate emerging threats.

Frontier Deterrence equips states to respond dynamically to the evolving global landscape. By fostering resilience, regional stability, and adaptive governance, this model enables nations to address not only immediate crises but also long-term systemic challenges such as climate migration, technological disruption, and the proliferation of transnational criminal networks.

This comprehensive and forward-thinking model offers more than a security strategy. It provides a vision for sustainable development and cooperation in an increasingly interconnected world. By embracing this approach, states can confidently navigate the complexities of migration and security, building a foundation for stability, equity, and shared prosperity.
