I will feel an inexplicable patriotic vindication if this news turns out to be true.
For that, you are waiting on ... which authority?
The U.S. gov't. claims it was ObL, with DNA verification. No national authority I'm aware of, friend or foe, is claiming otherwise. The body has been dumped. For whatever reason (likely to avoid some kinda ugly spectacles), no photos have been released.
Indeed, the US government has a lot to lose if it is proven that there is a variance between the truth and the facts as they related them. It would probably decide the outcome of the next US election.
I think it would be important to consider certain variables when thinking about how much weight 'no national authority is counter-claiming':
1- What is the benefit of pissing off the USA by making this counterclaim? It is a bit of a diplomatic faux-pas to challenge the truth of an announcement very important to the world's most powerful nation.
2- Believing that the event took place as reported so far is subjective. The evidence produced is...well, not there.
3- The information has yet to be independently verified. Convenient that the body was disposed of within 24 hours.
4- DNA evidence? Unless I'm mistaken, doesn't that take several days to process (i.e. without a queue ahead of you, once it gets to the lab), like at least 5-10? I don't suppose they went in and collected DNA evidence before the strike, what do you think? If they collected it on Sunday, it would be approaching 3 days now.
Edit: Further research suggests there are methods of DNA identification that can be done within 24hrs, so I think point 4 loses strength there.
Anyway, assuming Osama bin Laden wasn't a
Goldstein from 1984, as some suggest he may have been, we'll probably get a new video posted of him saying 'you got the wrong guy'...
From the sounds of things, they're as certain as they can be; the administration has now staked its credibility on the truth of its claim. Unless you believe the conspiracy theorists, in which case I humbly submit that nothing will ever convince you, this looks to be as sure as it gets.
They are not as certain as they can be. When evidence is produced the claim becomes more believable. The absence of counter-claims does not necessarily add to the veracity of an argument.
