Discussion Questions: There are multiple threats vectors to the world's maritime transportation system (MTS) and their associated ports from small boat attacks to the possibility of CBRNE attacks. For this forum, consider what these threat vectors are, what challenges are present in detecting these concerns and what security/industry at all levels are doing to address them. You response should be holistic and consider this issue from the strategic, operational and tactical level. Consider the impact and importance of the development of Mega Ports, the widening of the Panama Canal, and the increased use of the western rivers of the United States as a means of moving large quantities of hazardous chemicals. It is imperative that you consider both man-made and natural threats to the MTS.
