I can't help wondering how many separate plans are 'in the works' at this very moment. One is too many.

Remember the Palestinean weapons and explosives shipment intercepted off Gaza?

The cargo was loaded into bouyed watertight cannisters for later pickup by Palestinean "fishing vessels".

Remember as well there was a similar incident around Christmas with a cargo ship near London, that turned out to be nothing.

And I believe SEALs have been involved in searching ships in the Indian Ocean; so while it's unusual near the US, SEALs boarding ships overall isn't completely unheard of.
