third border
n.— «Further, the US now can be expected to more intensely monitor the entire Caribbean region’s security arrangements. In the past, efforts to strengthen the Caribbean’s security systems have been directed at pursuing drug traffickers and their money, and in some cases, such as Haiti, impeding an outflow of illegal aliens. Despite its advocacy of a “third border” concept—which views the Caribbean as another border area besides Mexico and Canada, requiring special treatment—the US had until now paid little policy attention to the area as an integral part of its fight against global terrorism.» —“A terrorist hub?” Economist.com (United Kingdom) June 6, 2007.
