Osamy boy promised that he wouldn't attack any of the states that voted for John Kerry.
Yes, and even though Muslims may freely lie to their adversaries (it's "In The Book"), his minions may well honor this promise, until it's convenient to break it with some followup excuse for why it's OK.
Meanwhile, the juiciest targets (highest small area large population density concentrations) are ALL in blue states: NYC, Boston, Baltimore-Washington(DC), Chicago, Seattle, Portland, San Francisco, Los Angeles, San Diego.
However there are plenty of other available targets: Houston and Dallas-FtWorth would be high on the list, and Phoenix, Atlanta, Miami, Orlando, Tampa, Charlotte, Raleigh, Greensboro, Nashville, Memphis, Indianapolis, Kansas City, Denver, Salt Lake City, Las Vegas. All are heavily populated target areas (counting the entire metro areas).
Recall that, before the spectacular attacks of 9/11, the previous largest attack was on the federal building at Oklahoma City. And that was just one, well-placed fuel-fertlizer bomb. It may even have been an early Islamofascist action, according to some analysts who have looked beyond the "official" case to evidence that was not followed up.
Anyway, Osama has plenty of large targets to choose from in the red states. Given the significant infiltration of "non-Latinos who can't speak English or Spanish" across our southern borders, and the ease of moving dangerous materials along with all of the other traffic that passes freely across the border, targets in the southwest and south might be most attractive, given that they are most accessible.
