So another catastrophic event to shake up the Middle East once again, it was bad enough with all these revolutions, now Al Qaeda is going to get pissed off and will want take action, and there are plenty of vacant places for them to set up shop.
I actually know a relative of Bin Laden; one of his great nephews, he's not really too happy about this news, most likely because of one of Bin Laden's sons also being killed in the raid, it could be a relative he was more closer to, sad really.
Plus, we don't really know that Osama felt no remorse. Sure he didn't show it, but he was (most likely) a faithful Muslim who believed it was the will of Allah to prevent the pressure and manipulation that the Americans were applying on them, no matter the cost. Maybe he felt remorse for their deaths, or even his faithful servants that followed him to the end, we actually don't know. What is known is that there are hundreds of people on the streets in the States celebrating the death of the man they hated so much, with no remorse for his eventual fall. Does that make them any more human than him?
And yes, this does happen to be a booster for Obama's presidential campaign, that's what happened with Bush, and America is well known for doing the same things over again. So yeah, black prez in the states for another four years, perhaps we'll him live up to his nobel prize this time round, now that main reason for hanging around in Afghanistan is gone.
Also, let's not forget that Obama did approve of the operation, as quoted, Obama signed an agreement to the operation calling for Osama "to be brought to justice". Whether that means that the operation was meant to capture him alive or kill him on the spot is unclear. Though it is something that most people are missing out in their celebrations; a Democratic Leader giving the all clear to have a man shot in his home and dragged back across the Atlantic. And having failed to bury him by Sundown, the deadline for having a man buried in Muslim Culture, is really going to piss off not just the Taliban, but many other Muslim people. We have some rocky times ahead of us.
As for the possibility of a fake, very unlikely. America wouldn't have said it out loud if they weren't sure, for Osama to pop out again and claim that he doped America once again would send its reputation crashing down. So they took DNA samples from as many of his relatives as possible, including the above mentioned, since they couldn't get his own. They put it all together to get a representation of what Osama's DNA would probably be like, it must have been a very close match for America to make such a bold claim.
So what happens next, Al Qaeda will most likely have a power vacuum, unless Osama's next of kin was already declared, and then they'll try again. The next guy might be more dangerous and cunning, and bring about another terrorist disaster for the States. Or he's too weak and Al Qaeda will eventually deteriorate into nothing.
