They are all headed to the persian gulf in the biggest naval deployment since 1991! what could it be? an Israeli news source speculates: http://www.debka.com/headline.php?hid=5499 1. The US, aided also by France, Britain and Canada, is finalizing preparations for a partial naval blockade to deny Iran imports of benzene and other refined oil products. This action would indicate that the Bush administration had thrown in the towel on stiff United Nations sanctions and decided to take matters in its own hands. 2. Iran, which imports 40 percent of its refined fuel products from Gulf neighbors, will retaliate for the embargo by shutting the Strait of Hormuz oil route chokepoint, in which case the US naval and air force stand ready to reopen the Strait and fight back any Iranian attempt to break through the blockade. 3. Washington is deploying forces as back-up for a possible Israeli military attack on Iranâ€™s nuclear installations. 4. A potential rush of events in which a US-led blockade, Israeli attack and Iranian reprisals pile up in a very short time and precipitate a major military crisis. 5. While a massive deployment of this nature calls for long planning, its occurrence at this time cannot be divorced from the flare-up of the Caucasian war between Russia and Georgia. While Russia has strengthened its stake in Caspian oil resources by its overwhelming military intervention against Georgia, the Americans are investing might in defending the primary Persian Gulf oil sources of the West and the Far East.
