My predictions:
Hostilities have not yet started in the Gulf, though the ultimatum delivered Monday ends in about 80 minutes.
But if I know Bush, he won't attack. Why? The element of surprise.
If you'll notice, he said hostilities would commence at a time of our choosing. The deadline will arrive... and then pass. Unceremoniously. And there will not yet be war.
We will wait. And there will not yet be war.
One day will pass, then two. A week. And a little before a fortnight later, there will be another press conference, at which Bush will reveal the grand purpose of his preparations for war.

To make the biggest April Fool's Prank. Ever.
