your post implies we should know all, even secret stuff.
The reason we know now is because the enemy knows and many are dead. The reason for secrecy is no longer required. dead bodies are the testimony
Bert,
You found an implication, “your post implies we should know all, even secret stuff,” that I did not imply.
I have spent many years as an Army intelligence officer and afterwards being involved with declassification. I will state that I do BELIEVE that 95% of all military classified has a expiration date after which it can and should be declassified.
