We have a statement for the record (pdf) from James R. Clapper, Director of National Intelligence, dated February 9, 2016. Perhaps it is the nature of the beast, but there is no good news, and much that is bad.
Smuggling of every type appears to be on the rise including drugs and people. We can expect an increase in illegal immigration as a result of violence, poverty, and disorder in Latin America and particularly Cuba and Central America.
It is a relatively compact document. There are sections on Terrorism (pp 4-6), transnational organized crime (pp 11-12), Arctic (p 13), Environmental Risks and Climate Change (pp 13-14), health (including potential pandemics) (pp 14-15), and Global Displacement, “These 60 million consist of approximately 20 million refugees, 38 million internally displaced persons (IDPs), and approximately 2 million stateless persons, also according to UNHCR statistics.” (p.15)
There are also regional assessments including one on Latin America and the Caribbean (pp 28-29).
There is no regional assessment for the US. In terms of direct terrorist threats to the US, while there is a recognition of an aspiration on the part of various groups to attack the US, but the emphasis seems to be on “homegrown violent extremists” (HVEs) and there is nothing about the possibility of a maritime attack on the US. Is that because none exist?
