The existing scholarship has widely examined security vulnerabilities and challenges within the forced migrant context. A myriad of factors along the complex trajectory of pre- and post-flight have contributed to a dire state of human security. Notably, the protection system has played a major role in the institutionalization of liminality and securitization, and inadvertently intensified refugees’ preexisting vulnerabilities. The literature on global institutions of protection within an evolving global migration landscape exposes the systemic securitization entrenched in the international instruments of protection; for the most part, the protection mechanisms are intrinsically exclusionary. There are also challenges and dilemmas of disentangling security from migration that render conceptual conflations and resultant mechanisms of institutionalization inevitable. Essentially, the architecture of the instruments of protection informs the mechanisms for response. The systemic contradictions within these regimes are therefore likely to be reflected and replicated in their operationalization. The overall dynamics expose humanitarianism and security first, as oppositional imperatives, and secondly, as enduring dilemmas that institutions of protection continuously reconciliate.
