What type of confirmation do you want? The documents aren't going to be declassified in the next couple of decades, if ever.
I've never heard anyone claim that Dual_EC_DRBG is most likely not intentionally backdoored, but there's literally no way to confirm because of how its written. If we can't analyze intention from the code, we can look at the broader context for clues. The NSA spent an unusual amount of effort trying to push forward an algorithm that kept getting shot down because it was slower than similar algorithms with no additional benefits (the $10 million deal specified it as a requirement [1]). If you give the NSA the benefit of the doubt, they spent a lot of time and money to... intentionally slow down random number generation?!
As an American, I'd prefer a competent NSA than an incompetent NSA that spends my tax dollars to make technology worse for literally no benefit...
