Sounds like Osama is planning to open a slick PR agency on Madison Avenue. And/or buy the NY Times.
Seriously, I've always thought that when obl nears death with his kidney disease, he'll take part in a suicide attack somewhere using the worst weapons he can buy. Might come in through Canada where the customs jerks couldn't care less. Blowing up Detroit would "divide" the USA and it's only an unguarded bridge away from Canada. (But so many muzzlims live in that area, he may not.) Private boat onto Great Lakes? Chicago? Divide into three parts suggests two attacks.
If somehow he kills himself on US soil, the muzzles will claim him as a big martyr and also claim the US as their own. Nasty.
Why does everybody assume the division will be physical rather than spiritual or ethnic
A series of assassinations of certain black and Hispanic leaders, coupled with some bombing operations by Black Muslims in malls crowded with Christmas shoppers would do quite a bit toward "dividing" the US into three parts (white, black, and brown)
