Wiseone has got it right that Iran has many ways to mess with the 2 mile wide shipping lanes through the Strait. We thought Korea, Vietnam, Iraq and Afghanistan would all be a walk in the park but it didn't work out that way. We're learning that asymmetric warfare doesn't fit into our battle plans and strategic maneuvering. If they manage to keep using anti-ship mines, suicide speedboats, torpedoes and missiles they could mess it up for awhile and that's all it would take to send the markets off. Everyone keeps telling me how logically the market has nothing to fear and I keep saying the markets aren't completely logical or they would've never invested in all those mortgage backed CDS's, causing the recession. They're crazy greedy and half based on illogical emotions, gut feelings, hunch's and plain old shrewd manipulating.
