AES-256 was broken in 2011.[1] While only four times faster than brute force and thus not a practical attack, it suggests that compromise is possible. The Snowden documents indicated that the NSA was working on breaking AES-256. It seems unlikely they would waste effort on a task they considered impossible. Whatever they achieve will be achievable by others eventually.

On top of that, no implementation is perfect. Bugs are discovered in cryptographic APIs on a regular basis. Even if your API is perfect, the application calling the API can have bugs that allow compromise.
