So there's a US Navy Armada headed for Iran, and Russia invades Georgia. Precursors for World War 3?

Or am I getting carried away? If the joint US/EU naval fleet embargoes Iran, that is an act of war under international law. Iran could declare war on the US and Iran after that and then it's possible Russia and China could back their ally. That would be disastrous. And Russia is already in recent conflict with former USSR member Georgia. All of this on 8/8/08, the day the world's attention is on the Olympics in China. Coincidence? I think not. But what do you think?
