Yeah I think I started writing before I really got your question, my apologies :)
It is very possible that government based research on crypto cracking is several years ahead of the rest of the world, but the attitude to these systems around the time of the dot com bubble was switching from security through obscurity to working in the open. The reason is the research cuts both ways, the US relies on AES as much as you or I. If there is a problem with it, they would be burned as well.
