The Command’s J-2 intelligence directorate reported recently in internal channels that “special interest aliens” are working with a known alien smuggling network in Latin America to reach the United States. The smuggling network was not identified.

Army Col. Lisa A. Garcia, a Southcom spokeswoman, did not address the intelligence report directly but said Sunni terrorist infiltration is a security concern.

“Networks that specialize in smuggling individuals from regions of terrorist concern, mainly from the Afghanistan-Pakistan region, the Middle East, and East Africa, are indeed a concern for Southcom and other interagency security partners who support our country’s national security,” Garcia told theWashington Free Beacon.

“There are major hubs that serve as entry points into the region for migrants from those areas of concern attempting to enter the U.S. along our border with Mexico,” she said.

The infiltrators from terrorist states and unstable regions exploit vulnerabilities in commercial transportation systems and immigration enforcement agencies in some of the countries used for transit, Garcia said.

“In 2015, we saw a total of 331,000 migrants enter the southwestern border between the U.S. and Mexico, of that we estimate more than 30,000 of those were from countries of terrorist concern,” she said.

Another problem in dealing with migrants from the Middle East, North Africa, and South Asia is a lack of information among the governments of the countries used by potential terrorists for transit.

The exploitation of alien smuggling networks by terrorists until recently had been dismissed by both American security officials and private security experts as largely an urban myth.

However, the Southcom intelligence report revealed that the threat of Islamist terror infiltration is no longer theoretical. “This makes the case for Trump’s wall,” said one American security official of the Southcom report. “These guys are doing whatever they want to get in the country.”
