Just as fear creates grounds for suspicion, it needs to be treated, both intellectually and politically, with suspicion. Unraveling the antecedents of fear is crucial to keep governments and other protagonists of nationalism in check. Without constant vigilance that probes the production of fear and crisis, both of these commodities will be used creatively and strategically to justify violence and exclusion. Insecurity expressed at scales of the body and household will remain largely effaced if militarized nationalisms continue to reproduce geopolitical life as a matter of nations and states, fear and violence.
