I'm not even convinced the NSA can get it. There are no side-channels to exploit here (which we know the NSA is good at) and cooperation from online services won't work either. The protocols used to encrypt this are fairly simple and well-understood and we should not assume that the NSA is capable of breaking the underlying (strong) primitives.

The NSA will just get your data off Dropbox by having a judge ask them nicely. That much is undeniable.

Whether or not they can break the Keepass encryption after getting your data is debatable but strikes me as "probably yes."
