This study provides an integrated explanatory analysis of ominous covert tr
ansnational flows and their implications for international security. After
delineating their scope and discussing their general causes and consequence
s, brief overviews of the four most important types of these transactions-c
landestine conventional arms, illegal human migration, illicit psychoactive
drugs, and unsanctioned hazardous waste-serve to illuminate the specific r
ecent patterns of this activity. The article concludes with a probing explo
ration of how these flows highlight hypocrisy in national policy and dysfun
ction in global rules of the game, challenging the security of the existing
world order.
