ABSTRACT
This chapter discusses mexican concerns, any conceivable military trilateralism as well as Mexico–U.S. and Mexico–Canada military cooperation could not entail, at least in the short run, classical international security cooperation: coordinating the ability of the military to use force or threatening to use force against other countries. The Canada–U.S. defense relationship, prompted by the twin security concerns of preventing hegemony in Eurasia and providing for defense at home. A common security region incorporated in a broader alliance with other countries, intense functional closeness between certain elements of the armed forces of both countries, and a desire on the part of both countries to limit the extent of the closeness. The North American air defense system was oriented northward, not southward, with the special exception of monitoring Cuba. With the disappearance of the Soviet Union, the threat to North America is also rapidly declining.
