This is an attempt to uncover the ways in which the Government of Sri Lanka (GoSL) securitized its response to the COVID-19 pandemic in 2020, and how that process of securitization functioned in furthering its overall approach to its legitimacy and governance. Regarding this, the article focuses on the language which characterizes the discourse and the references made to the Sri Lankan armed conflict. Using Critical Discourse Analysis (CDA), written and audio-visual texts from government media outlets, private media outlets, and English news articles are assessed in this article as primary data. The discourse on the studied corpus reveals how the State securitized its response to COVID-19 as one befitting a military threat rather than a public health risk. In militarizing the securitizing process, the police and triforces were deployed as first respondents. References made to their experience in defeating the Liberation Tigers of Tamil Eelam (LTTE), as well as to former President Gotabaya Rajapaksa’s role as Defence Secretary in the armed conflict against the LTTE, were used in legitimizing the process of securitization. References made to the “sacrifices” made by the State, and the military, by extension, were used in instilling a sense of responsibility among the public to show their support for the government in its attempt to grapple with the pandemic. The public were also asked to act in unison which included an implied demand for discarding their diverse identities. This article further reveals a novel form of religious securitization emerging from the studied corpus in relation to GoSL’s response to the COVID-19 pandemic.
