Contemporary North American insecurities and fears are the focus of this article. In the first section, the inter-related concepts of insecurity, fear and vulnerability are theorised, and the argument put forward that these have come to constitute a dominant discourse in contemporary North American society. In the second section of the paper, the components of this discourse are presented by reviewing what North Americans fear, including terrorism, crime and violence, and the "Other". Comparisons and local manifestations of this discourse in Canada, Mexico and the US are described. The final section turns to the educational implications (effects) of this discourse as it has been taken up across the three nations. While other comparativists have focused on phenomena such as globalisation and neo-liberalism to explain contemporary education reform, the author argues that it is the discourse of fear and insecurity that now underpins educational reform.
