Stealth technology was kept secret for about 20 years, and then of course are the secrets that we don't even know about... How can you measure their
success in keeping secrets if you don't know about the ones that they HAVE kept secret?
And then there is the definition of a secret. Lets take the 9/11 massacre for example, probably one of the gov't biggest modern secrets. Is it still
a secret? Yes and no, it depends on what you believe.
You can fool some of the people all of the time, and all of the people some of the time, but you can not fool all of the people all of the time.
