The EC country where the terrorist obtained his CBI passport could immediately be subject to sanctions, as well as negative publicity that would impact tourism and trade, which one analysis described as akin to pariah status by EU and North American governments. This might make international trade extremely difficult, compounded by the fact that the economies of the East Caribbean nations are dependent upon imports.
Unless the East Caribbean states with CBI/CIP programs wish to be treated like the West did for years with the apartheid regime in South Africa, the due diligence investigations conducted upon all CBI applicants:
(1) Must immediately be upgraded to enhanced due diligence (EDD), to include confirmation of identity, using social media and social networking resources, accessed through facial recognition software systems (FRS).
(2) A historical look back of existing CBI passport holders, to include, but not be limited to, EDD and FRS checks of social media resources, to either confirm identity of the passport holder, or the public cancellation of his passport.
If the Five East Caribbean CBI states do not choose to upgrade their due diligence, as we have detailed above, then they should not be surprised when a Specially Designated Global Terrorist (SDGT) organization obtains their passports, and uses them to commit a deadly terrorist act. The consequences could be fatal for the local economy of the offending country, and if the United States is the victim, look for a full-court direct response forthwith.
