Why would you think that? The US government may not have too many
clues, but they certainly understand the importance of crypto. I cannot
think of any reason to suppose that NSA et al would have stopped
spending serious effort in this area. (Where "serious effort" is
measured by the standard of "a billion here, a billion there, pretty
soon you're talking about real money".)
Quite honestly, as a US taxpayer I would not be happy if the NSA were
not far ahead of public research in this field ...
