how are you going to stop their full time and only business?
My solution:
(.)bama issues declaration: free all americans and their vessels within six hours. Clock is ticking as I sign off.
If not, welcome to your heaven. (of course (.)bama would never do this.)
Then after six hours of them jumping up and down shooting their AK47s into the sky, EAM to closest SSBN: Spin up one D-5, target Somalia. Set yield at maximum for the 7 MK5s, ground burst. Fire when ready.
30 minutes later while firing their weapons, flash spotted just before they melt.
That problem solved. Deep water port of Kenya now open for business.
