As I started to write the conclusion to this book, I noticed that one of my colleagues down the hall in our office building at San Diego State University had a cartoon on her door that succinctly illustrated where immigration phobia may take us if it comes to inform public policy on immigration. The publication date was cut out, but it was clearly done some time after the September 11, 2001 terrorist attacks on the United States. Originally published in The Miami Herald, this syndicated cartoon warned that overreaction to post-9/11 threats could reverse the very identity of the United States as a nation of immigrants. In the artist's grim portrayal, the Statue of Liberty had a new inscription, asking the world to give America not the “huddled masses,” but metal detectors, frisks, illegal searches, I.D. spot checks, and the “scared people yearning to feel safe.” Somehow, after conducting years of comparative research on antiimmigrant hostility I could not dismiss this unflattering dystopia as an artist's fantasy. This chapter scans broader and more nuanced policy implications of immigration phobia, but the concerns that this analysis raises resonate profoundly with the one raised in the Statue of Liberty cartoon. Specifically, it focuses on four major issues: (1) the distinct role of the core security-dilemma perceptions (emergent anarchy and intent offensiveness) in the formation of antimigrant hostility; (2) the added value of the security-dilemma perspective with respect to major existing theories of interethnic conflict; (3) implications of this study for research on early warning and prevention of ethnopolitical conflict; and (4) immigration policy implications.
