The World Trib has broken the story that the US has relayed to our troops that March 18 is a go:

The U.S. military has been ordered to launch a war against Iraq on March 18, an Israeli official said in a televised report.

Israeli government monitor, Michael Gurdus, reported on late Tuesday that the order was relayed by U.S. Central Command to all American forces in the Persian Gulf. Gurdus told Israel's Channel 2 television that he heard the order being relayed to U.S. fighter-jet pilots and others over U.S. military radio communications he intercepted.

Take that with whatever sized grain of salt you wish. I just have to say, Let's get it on.
