Provides an integrated explanatory analysis of the new global security environment, attempting to detect and evaluate broad overarching patterns. Begins by discussing the general nature of the emerging global security environment and the transfers that occur within it, then turns to analysis of causes, consequences, and futile cures associated with these transnational flows. Overviews the most important flows, such as illegal migration, illicit drugs, and infectious diseases, and highlights the national hypocrisy associated with them. Suggests ideas for augmenting conventional ways of responding to these kinds of threats.
