I agree with your post
("Due to poor skippering by a captain of Her Majesty's fleet, our small flotilla made an inadvertent course correction that actually minimally entered Iran waters.")
except 1 or 2 items you forgot.
The 1 or 2 nukes that hit iran after the sailors come home.
If they really play this game with Iran, Achmadinejad will think he's got a brass pair.
There is no telling what he will do after that.
I keep asking myself what we would do in this same situation and I fear the Libs would dominate the discussion via the MSM and neuter us.
