Submarine Terrorism Plots in Progress?
Consider the nature of two "buyers" that we know about:
North Korea agrees to supply 4 mini-submarines.
Moro Islamic Liberation Front (MILF), the Islamist terrorist group and the largest guerrilla movement in the Philippines.
North Korea had already indicated that it would sell one or more mini-submarines to the MILF, but has yet to deliver. North Korea hesitates because U.S. and Philippine intelligence sources discovered the deal. The MILF made a $1 million downpayment and still owes $1.2 million on its mini-sub buy.
Next, consider the al-Qaeda Submarine Threat to oil terminals, including the world’s largest offshore oil export terminal at Ra's Tannūrah (Ras Tanura).
More mundane dive targets were discussed here, recently.
Not mentioned, however, is the use of mini-submarines (obviously ideal) for delivery of suitcase, nuclear bombs to waiting SUVs in North American coastal areas. Or worse, deliveries of lethal biological agents to aquifers or water supplies. Not a threat, you say... well the FBI recently alerted U.S. dive shops toward suspicious divers, bubbleless equipment and underwater vehicles. Draw your own conclusions.
Submarines are always silent and strange.
