If true - and we'll assume it is for the moment - then this story is really significant. It not only shows daring, but the technological capability to pull off such a stunt. Something which ought to keep every USA warship commander in the region awake at night. This was no suicide stunt. They snuck in, tagged the ship, and snuck out. Alive. Next time they'll exchange a limpet mine for a spray can.... and you can kiss a whole aircraft carrier goodbye. (Unless of course this whole story is a BlackOps disinformation trick by USIsrael.... seeking to create a PearlHarbour attack event fore-runner propaganda - in an Israeli newspaper. So when they destroy one of their own ships to justify an Iran attack... they can point to this story. Who knows.
