Moving away from the blame game for a minute, really? Are you accentuating the United States part of the sentence? If so, why? It's a natural disaster. Granted we are God's Chosen Country, but I think the intelligent design module is set to automatic on the natural disaster component.
Not that I think of this stuff with any frequency, but I would imagine that a major earthquake on the West Coast, the big one, iyw, will result in a far greater devastation. I am fairly certain that there are models that predict more than 25K deaths.
Unfortunately, but possible.
And, of course, it will be Bush's fault.
