Someone on Fox News just commented on the naval fleet you mentioned sometime back. He believes they may be planning a blockade against Iran and maybe North Korea. Apparemtly there has been a radioactive spill at Tehran airport (and why they won't let inspectors in, i.e. they don't know how to clean it up fast enough. That new airport is closed. They suspect N. Korea provided the material, and despite what Iran says, they are continuing their centrifuge operations. Things are really heating up. If nothing goes in or out of Iran (including oil), oil prices just might move up, though right now, they appear to want to go down. Better buy gold soon.
