So... There are several people in possession of a information that has a value and that has been publicly identified as valuable.
No problem. Governments only hire people immune to corruption.
There's an important difference. Yes, this information can be obtained by a determined adversary with considerable resources. Making it public, however, would mean every blabbering fool in a cave with an Internet connection has it.
That is quite a difference. We're all constantly going on about how we realize that there's no 100% security - this is just such a case. Making critical information hard to obtain is precisely what security is all about.
