A few personal thoughts shared:
1. What value can you put on reaching the moon first? Did this help future US Scientists and Engineers believe they can do anything. Of course it did.
2. How did Russia succeed with Mir (we're led to believe in the West that this was a huge failure...nonsense). Scientists and Cosmonaughts were paid jack. Mir fell apart due to a collapse of the USSR. Prior to that it was resources and brilliance. [Nasa spends millions designing a pen to use in space, Russia uses a pencil]. What signal will a US cancel show the world?
3. Dual technologies. Nuff said.
4. Helium 3 mining. Few people realise that if all types of power plants currently operating worldwide switched to Nuclear, we'd run out of Uranium in 100 years. Hmm then what... (Ok we can scrape the reactor walls for a long long time).
5. US Black budget. Haven't been back for 37 years? I wonder...

Wasn't the B-2 designed and built with total secrecy....I'm not sure.
